tmp <- function(s) { return(str(s)) } key <- "xxxx-yyyy" tmp(key) # chr "xxxx-yyyy" ... works for me. Reprex? Cheers, Boris

You are the domain expert, but it would seem to me that "-NEGRO" is a part of the ID because it uniquely specifies the product.

> sum(x, na.rm=!all(is.na(x))) That's the kind of idiom that brings the poor chap who has to maintain it to tears. ;-)

Could someone kindly enlighten me whether there are currently advantages to use R Studio vs. the normal R GUI? On the Mac I can't seem to find anything compelling, on Windows (which I don't use myself) I noticed...

Or ... if you mean "simpler" as in "less to type", you can define your own binary operator by enclosing it in "%" signs, and the assign any of the previously proposed solutions, e.g. y = matrix(cbind(c(0, 0.5...

The help text for row+colnames {base} states: "For a data frame, rownames and colnames eventually call row.names and names respectively, but the latter are preferred." Why are they "preferred"? Why is it names(), not col.names()? I have...

I've recently been getting freezes while editing a script file and noticed on this list that the current R version is 3.1.2 (I was on 3.1.1). "Check for updates" had reported R 3.1.1...

I was just surprised by very un-intuitive behaviour of paste(), which appears to collapse a one-column data frame or one-element list into a deparsed expression, rather than producing the expected string. Can someone kindly explain what's...
