Extracting value from csv file with condition using if else and & operator

I have a csv file and I would like to extract the value of it with specific range for example; F>2 & F<2 & P=1, and then write the result to csv file.

I tried the code bellow but , it does not work?

FCPval <- read.csv("C:/Users/shawin/Desktop/RProgramms/RAdipose/FCPval.csv")
c=as.data.frame(FCPval)
for (i in 1:rowN){if (C$F[i] >= 2 && C$F[i]<=-2&& C$p[i]<=3){
  dfrmPFC=data.frame(Fc=FC,p=p)}
}

The error is:

Error in C$FC : object of type 'closure' is not subsettable

It seems this is a duplicate post (Extracting column value from csv file according to if else and & operator ), you should probably remove one or the other :S

Also it's not really a bioinformatics question but more an R problem. But it seems you are not consistently using capital and small letters, you created a data.frame named c but you want to access it using C for example or have a column Fc and then try to call $F... Maybe you should do a small R tutorial first before trying to do anything. Grtz!

Sorry it's a typing error, and I mistakenly posted twice

R is case sensitive, so c and C are different. Also, the code you showed will never produce the error you wrote. Finally, help(subset).
