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.
