Hi, In my function, I want to allow input to be a vector or a data.frame. Certain operations need to be done if the length or nrows exceeds one, but since "nrow" doesn't work for vectors, I cannot simply use
if( nrow(input)>1 | length(input)>1 ) ... So is there a more elegant way to do this then with the following code? if( if(is.vector(input)) length(input)>1 else nrow(input)>1 ) ... thanks ahead, Berry ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
