153 133 145 111
189 177 200 170
221 241 187 243
215 228 201 178
302 283 292 248

201 238 233 163
173 164 172 139
121 128 119 120
100 200 300 400"
# read in data
d <- read.table(textConnection(Lines), header = TRUE)
#add row.names
row.names(d)=paste("trial_number",sprintf("%02d",as.numeric(row.names(d))),sep="")
# view output
print(d)
