Does anyone know if there's an easy facility to create and specify a template
file to be used for new R scripts?
I found myself creating this function which works well (in RStudio on Windows).
newR = function(filename=tempfile(tmpdir='.',fileext='.R'), open=TRUE) {
template = paste(Sys.getenv('R_USER'), 'R_template.R', sep='/')
lines = readLines(template)
lines = sub('Sys.time', format(Sys.time(), '%A, %d %B %Y'), lines)
lines = sub('getwd', getwd(), lines)
lines = sub('R.version.string', R.version.string, lines)
writeLines(lines, filename)
if (open) shell.exec(filename)
filename
}
Rather than the default of an empty file, it would be good practice to start
with a structured template script. Such a template might contain opening
comments (author, date, project folder, aims, inputs, outputs etc.) and section
comment headings for the various components of what a script does (load
packages, get data, process data, produce outputs).
cheers,
Steve
