I think I will do the same...................
Thanks to Jim I learned "textConnection" and "rowMeans".
Jim, could you please go a step further and tell me how to use lapply to
calculate
the sd instead of the mean of the same items?
I mean
sd(-0.6442149 0.02354036 -1.40362589)
sd(-1.1829260 1.17099178 -0.046778203)
sd(-0.2047012 -1.36186952 0.13045724)
etc
x <- read.table(textConnection(" v1 v2 v3 v4 v5 v6 v7 v8
NA -0.6442149 0.02354036 -1.40362589 -1.1829260 1.17099178 -0.046778203 NA
