you can combine write and write.table, using append=TRUE.
e.g.,
write1 <- function(txt, mat, filename) {
for(i in 1:length(txt)) {
write(txt[i], file=filename, append=i!=1)
write.table(mat[[i]], file=filename, append=TRUE,sep ="\t")
}
}
t <- c("text1", "text2", "text3")
m <- list(matrix(0,2,2), matrix(1,2,1), matrix(2,3,2))
write1(t, m, "x.txt")
