Running Compile Notebook from RStudio.
I am getting:
Error: could not find function "SegNeigh"
"SegNeigh" being my own function, properly sourced; the script runs fine without R Markdown.
Any help appreciated.
In order for the rmarkdown doc to find the function, you either need to define SegNeigh in the same document or place it in another file and source that file explicitly

Unfortunately I have to deal with a data file with .int file format. This has the effect of littering any search results with unrelated information about integers.
I can't figure out how to open this file in R. I have an example with the Julia language, shown below:
filename = "mnist_train.int"
open(filename) do f
...
end
But when I try to search for a similar function in R, I either find results about opening excel files, results for other languages, or results that deal with integers. Could someone please point me to some resources for dealing with this filetype?
Because I am not sure about what the content type, guess you trying to open a binary file format.
You can have a look at ?readBin

Is there a function such as kable to output character vectors in a way that doesn't look as ugly as the default console type?
See eg p from the pander package or the generic pander method:
> pander::pander(sample(letters, 5))
_p_, _r_, _v_, _f_ and _t_
If you want to override the default formatting, see panderOptions or specify directly in the p function.

I inherited legacy code from 2009 that includes the many of the following types of expressions -
variable %in% cs(do, ph, t, secchi)
I get the following error - Error: could not find function "cs" when I try to run anything like this, have not seen 'cs' before, and can't locate any info in help files, google, or on this site so far. I'm guessing it is a deprecated way of concatenating strings but would like to confirm before I update the legacy code.
There is a Cs function in Hmisc package. I think it is that.
See this
library(Hmisc)
Cs(a,cat,dog)
