Hello everyone,
I am wanting to replace an element in a matrix with NA. I have used the
following code
dat<-read.table(file="C:\\Documents and Settings\\....txt",header=T,row.names=1)
file.show(file="C:\\Documents and Settings\\....txt")
Z.matrix<-as.matrix(dat)
Y<-dat[,46:63]
X<-dat[1,51]
dat[1,51]<-NA
Whenever I use this code I get the original value when I type show(X).I run the
script and type
show(X) and the original value is still there.What am I doing wrong?
Thank you
Paul
