...cinct. I'm trying to do this via the 'levels' command as I figured that I might be able to apply the character strings in a similar way to how you recommended when dealing with 'colnames'.
# Refine names of rivers to make more succinct
riv_names <- get(paste("arunoff_",table_year, sep=''))[,1]
levels(riv_names) <- c("AMAZON", "AMUR", "CONGO", "LENA", "MISSISSIPPI", "NIGER", "NILE", "OB", "PARANA", "YANGTZE", "YENISEI", "ZAM...
