[R] matching-case sensitivity

Hi All,

I am trying to match two character arrays (email lists) using either
pmatch(), match() or charmatch() functions. However the function is
"missing" some matches due to differences in the cases of some letters
between the two arrays. Is there any way to disable case sensitivity or is
there an entirely better way to match two character arrays that have
identical entries but written in different case?
