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

Removing leading and trailing blanks might be achieved through the trim() function from the gdata package as well:

require(gdata)
example(trim)

Usage example:

> trim("   Remove leading and trailing blanks    ")
[1] "Remove leading and trailing blanks"
