How can I trim leading and trailing white space?

Question

I am having some troubles with leading and trailing white space in a data.frame.

For example, I like to take a look at a specific row in a data.fra

Answer 1

To manipulate the white space, use str_trim() in the stringr package. The package has manual dated Feb 15, 2013 and is in CRAN. The function can also handle string vectors.

install.packages("stringr", dependencies=TRUE)
require(stringr)
example(str_trim)
d4$clean2<-str_trim(d4$V2)
