Hi,
your example is quite messy (neither reproducible or minimal). I think
you could try the following,
mdf <- data.frame(1:3)
names(mdf) <- "147"
i <- 147
mdf[ as.character(i) ]
Hope this helps,
baptiste

I think you have to convert the loop value to character; it is not
recognized inside the quotes:
#doesn't work, but now it should
i<-147
p1 <- grep("QueryItem",c1data[as.character(i),],value=FALSE,fixed=FALSE)
print(p1) # prints 0
Same thing goes for the 'for' loop:
for(i in 137:270) {
print(i)
Hi everyone
I am trying to use grep in a for loop to compare a string value. It works
if I use
the actual index value but when I use the for loop index, it doesn't work.
Any suggestions plz.
Here is the code:
data <- read.table(file="Sigmoid.csv", head=FALSE, sep=",");
c1 <- data$V1
c2 <- dat
Thanks very much Phil :)
Worked prefect
