Is there any way to remove at the same time several variables that share a suffix, for example (similar to * or ? in DOS) ?
To remove objects sharing a suffix use something like:
remove(list=objects(pattern="SUFFIX$"))
To remove variables sharing a suffix from a dataframe use something like:
newdata <- mydata[,-grep("SUFFIX$", names(mydata))]
In both cases the $ metacharacter indicates that the literal characters are at the end of the string.
hope this helps,
