I have a data frame containing variables "yr3",...,"yr28". How do I remove them with a wild card----something similar to "del yr*" in Windows/doc? Thank you. > colnames(mydata) ? [1] "year"?????? "weight"???? "confeduc"?? "confothr" "college" ? [6] ... ?[41] "yr3"??????? "yr4"???????

You'll want to use grep() or grepl(). By default, grep() uses extended regular expressions to find matches, but you can also use perl regular expressions and globbing (after converting to a regular expression). For example: grepl("^yr", colnames(mydata)) will tell you which 'colnames' start with "yr". If you'd rather you use globbing:

x["V2"] is more efficient than using drop=FALSE, and perfectly normal syntax (data frames are lists of columns). I would ignore the naysayers, or put a comment in if you want to accelerate their uptake. As I understand it, one of the main reasons tibbles exist is because of drop=TRUE. List-slice (single-dimension) indexing works equally well with both standard and tibble types of data

I am in the process of converting from Matlab to R, but a major sticking point for me at the moment is accessing data via OPeNDAP. After several hours of searching, I found that other people have discussed this functionality in the past, but it does not appear to have yet been developed. One programmer, Luke Miller, has managed a work-around by downloading ascii data from an OPeNDAP site (
