In the first part of this post I introduced several functions available in the package inSilecoMisc. In this post, I keep on introducing features of the package you might find useful! If you did not read the first part of this post and are interested in reproducing the examples below, simply install inSilecoMisc:

# Run if package is not already installed
install.packages("remotes")
remotes::install_github("inSileco/inSilecoMisc")

Load it:

3

library("inSilecoMisc")
packageVersion("inSilecoMisc")
#R>  [1] '0.7.0.9000'

and you’re good to go!

scaleWithin()

I wrote scaleWithin() to handle color scales for a specific yet frequent situation. Let us say that I have 40 percentage values – meaning 0 to 100 – in a vector val…

val <- runif(40, 0, 100)
val
#R>   [1] 26.573649 34.795546  9.567024 68.476367 63.501142 26.712777 44.280337 77.359206 89.927479

#R>  [19] 54.722567 70.881171 15.093481 35.835674 26.560072 42.294943 13.334883 89.972614 36.207392
#R>  [28] 36.215295 55.992105 68.838813 99.917928 46.417413 12.199940 31.912944 17.875707 66.026564
#R>  [37] 98.512163 45.560768 53.162744 33.468375

… and that I wish to create a color scale with 25 tones. I use showPalette() to show the color palette:

1
2

pal <- colorRampPalette(c("#f9fa98", "#500127"))(25)
graphicsutils::showPalette(pal)

But the color scale should be used for the range [30%-70%], meaning that values below 30% should have the lowest values and values above 70%, the highest one. The caption should thus indicate \(\geqslant\) 30% and \(\leqslant\) 70%. Then the function scaleWithin() is very handy!

scaleWithin(val, n = 25, mn = 30, mx = 70)
#R>   [1]  1  3  1 25 21  1  9 25 25 20 11  6  1 12 25 25 25 25 16 25  1  4  1  8  1 25  4  4 17 25 25 11
#R>  [33]  1  2  1 23 25 10 15  3
graphicsutils::showPalette(pal[scaleWithin(val, n = 25, mn = 30, mx = 70)], add_codecolor = FALSE)

Even though this function is pretty useful – at least I think it is! – I had a lot of trouble conveying why! So, in the last version of inSilecoMisc, I re-wrote the entire documentation and I hope that, together with this example, others will, as I so, find it useful.

Messages

Daily, I use R packages and R functions to analyze data, create model, run simulations, and a number of other things! So I write scripts that combine functions from various packages to create pipelines that do the analyses I need. When running such scripts, I like having information reported on a clear and visual way, that is why I value packages such as progress, crayon and cli. In inSilecoMisc, inspired by messages reported by devtools when building a package, I created four simple message functions using crayon and cli packages to standardize messages in my scripts.

1

3

# 1. msgInfo() indicates what the upcoming computation
msgInfo("this is what's gonna happen next")
#R>  ℹ this is what's gonna happen next

1
2
3

# 2. msgWarning() reminds me something important that should not affect the run
msgWarning("Got to be careful")
#R>  ⚠ Got to be careful

1
2
3

# 3. msgError() when something went wrong (and I anticipated that it could happen)
msgError("Something wrong")
#R>  ✖ Something wrong

1
2
3

# 4. msgSuccess() when a step/ a computation has been successfully completed
msgSuccess("All good")
#R>  ✔ All good

These functions help me structure my scripts. Here is a contrived example:

scr_min <- function() {
  # msgInfo() lets me know where I am in the script
  msgInfo("Average random values")
  set.seed(111)
  out <- mean(runif(100))
  msgSuccess("Done!")
  # msgSuccess() indicates the successful completion of this part
  out
}
scr_min()
#R>  ℹ Average random values
#R>  ✔ Done!
#R>  [1] 0.4895239

Another helpful aspect of these functions is that they all are based on message(). As such, if I want to execute a script quietly, all I need to do is to call suppressMessages() beforehand

1

# quiet run
suppressMessages(scr_min())
#R>  [1] 0.4895239

If you want to see an example of how I use these functions in a script for a scientific manuscript, check out the research compendium coocNotInteract.

tblDown()

Last but not least, I’d like to introduce a function to quickly write table data frame (or a list of data frames) in documents of various formats. I created tblDown() for a colleague of mine that was looking for a quick way to export a table. In the package knitr, there is the very handy function kable() that quickly writes a data frame in various formats.

1

knitr::kable(head(CO2))

I wrote a function that calls kable() to write the data frame and then renders the table(s) in the desired format indicated by the extension of the output file (docx by default) using pandoc.

1
2

# NB tblDown(head(CO2)) returns table.docx by default
tblDown(head(CO2), output_file = "table.odt")

As I mentioned above tblDown() handles lists of data frames and the user can also provide a set of captions for every table and even separate them with section headers (of level 1).

1
2
3

tblDown(list(head(CO2), tail(CO2)), output_file = "tables.pdf",
  caption = c("This is the head of CO2", "This is the tail of CO2"),
  section = "Table")

Check out the output file ➡️ ! Note that in the example above I only use one character string for section and tblDown() has appended an index; this is also the default behavior for caption: if there are less captions or sections titles than data frames, vectors of captions (and/or sections) are repeated and an index is appended.

If you are already writing your documents with R Markdown, you may not need this. Yet keep in mind that tblDown() quickly exports tables in various formats with only one line of command!

That’s all folks 🎉!
