[R] obtaining a true/false vector with combination of strsplit, length, unlist,

[Sarah Goslee]

You are so very close:
> sapply(edm[,1], function(x)length(strsplit(as.character(x), "_")[[1]]) == 3)
[1] FALSE FALSE  TRUE  TRUE  TRUE  TRUE FALSE

Thanks for providing a small reproducible example. dput() tends
to work better for than than textConnection(), because many email
clients add arbitrary newlines, messing up the text formatting.
