Hi,
I am trying to debug the following code:
for (i in 1:10){
t <- paste("d0$V",i,sep="")
t <- ifelse(regexpr(d1[i,1],d0$X0)>0,1,0)
}
and I would like to see what code is actually processing R, how can I do
that?
More to the point, I am trying to update my variables d0$V1 to d0$V10
according to the presence or absence of some text (contained in the file
d1) within the d0$X0 variable.
The code seem to run ok, if I add print(table(t)) within the loop I can see
that the ifelse procedure is working and to some cases within the d0$V1 to
d0$V10 variable range a 1 is assigned. But when checking my d0$V1 to d0$V10
after the for loop they are all still equal to zero...
Thanks,
Luca
