I've been wondering what L means in the R computing context, and was
wondering if someone could point me to a reference where I could read about
it, or tell me what it's called so that I can search for it myself. (L by
itself is a little too general for a search term).
It means that the number is an integer (a _L_ong integer of 32 bit actually)
I encounter it in strange places, most recently in the "save" documentation.
save(..., list = character(0L),
file = stop("'file' must be specified"),
ascii = FALSE, version = NULL, envir = parent.frame(),
compress = !ascii, compression_level,
eval.promises = TRUE, precheck = TRUE)
I remember that you can also find it when you step inside an apply function:
sapply(1:10, function(x)browser())
Called from: FUN(1:10[[1L]], ...)
I apologize for being vague, it's just something that I would like to
understand about the R language (the R word).
Thank you!
