Dear Researchers,

I have a data frame with several column with the name letters more of 8
characters. I wish to convert in a shape-file but there is a problem because
the names of the columns are more the 8 letters limit. Is there a function
to trunk the names is a data.frame?

this is a easy example

mydf <-
data.frame(mydatainfield=c(1,2,3,4,5),mydatainlab=c(1,2,3,4,5),intensity=c(1,2,3,4,5))

thanks in advance
Gianni
