Dear Readers, I amd not so sure if this is the best site to ask this question, but does anybody know why Rweb can''t recognize read.table command? I installed Rweb on local host machine. I made this input file as ''/tmp/data.txt''. a b c d a 0 1 3 2 b 1 0 1 1 c 3 1 0 2 R can recognaize the following command 1 ###command 1### library(mva) d<-read.table(file ="/tmp/data.txt") c<-hclust(as.dist(d),method=''average'') plot(c,hang=-1) ################ but, Rweb doesn''t responde to this script. Rweb can recognize command 2 ###command 2### read.csv(file ="/tmp/data.txt", header = T , sep = "\t") ############### but, ###command 3### library(mva) d<-read.csv(file ="/tmp/data.txt", header = T , sep = "\t") c<-hclust(as.dist(d),method=''average'') plot(c,hang=-1) ############### doesn''t seem to be a correct script. So, my question is (1)Why Rweb can''t understand read.table command (2)Please correct command 3 in right form. ****************************************** Akira Onozuka Researcher, Bioinformatics Screening Technology, Research Center Kyoto Bayer Yakuhin Ltd.
