And there are worked examples about how to tell R the correct encoding on 
the file() help page (as referenced from the read.table() help page).  If 
this is a Windows Spanish text file, the required encoding is most likely 
CP1252, so try

con <- file(<filename>, encoding="CP1252")
read.delim2(con, header=TRUE)
close(con)
