Use trim from:
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/40714.html
or trim from gdata or trimWhiteSpace from limma in BioConductor.
RSiteSearch("trim") and help.search("trim") can locate such functions.
s <- c(" abc ", " def ") # vector
m <- cbind(a = s, b = s) # matrix
DF <- as.data.frame(m) # data.frame
trim(s)
trim(m)
DF[] <- lapply(DF, trim)
