Hi Thomas,
If "x" contains your current results, one way to do what you want is the
following:
# data
x <- read.table(textConnection("X2403,0.006049271
X2403,0.000118622
X2403,50.99600705
X2403,7.62E-150
X2419,0.012464215
X2419,9.07E-05
X2419,137.4022573
X2419,6.45E-273"), sep = ",")
closeAllConnections()
x
# results
data.frame(output = with(x, tapply(V2, V1, paste, sep = "", collapse =
',')))
HTH,
Jorge
