Hi
IS is data frame so it is not numeric.
try str(IS) to see structure of your data.
maybe just
mat.IS <- as.matrix(IS)
gives you desired result, but it depends on (undisclosed) IS structure
BTW, do not use html formatting, it is useless in this list
BTW2, you should spend at least few minutes to read basic docs, kindly
offered by R-core in doc directory, especially R-intro which gives you quick
info about objects and their properties.
BTW3, your read.table is lacking header and sep and maybe dec specification
so I doubt it reads your data properly.
Cheers
Petr
