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$V1
c2 <- data$V2
c3 <- data$V3
c1data <- data.frame(c1);
c2data <- data.frame(c2);
c3data <- data.frame(c3);
#this works
p <- grep("QueryItem",c1data["147",],value=FALSE,fixed=FALSE)
print(p) # print 1
#doesn't work
i<-147
p1 <- grep("QueryItem",c1data["i",],value=FALSE,fixed=FALSE)
print(p1) # prints 0
for(i in 137:270) {
print(i)
p <- grep("QueryItem",c1data["i",],value=FALSE,fixed=FALSE)
p2 <- p
print(p2)
if(length(p)>0) { print(p) }
}
