I am new to R and I am having a hard time understanding and making the following snippet functional :
fMatrix <- DT[c(v1,v2), ] %.% select(f1,f2,f3) %.% lapply(...)
logically, it seems to make sense, as it is (probably) trying to take a subset and perform certain operations by some sort of method chaining using (dot operator). The problem is my R interpreter doesn't recognizes %.%
I am guessing the operator comes from a package I didn't import or something like that. Any insights are welcome.
Look at librarydplyr
, in R. The docs say it is related to chain
See the dplyr docs here, at p.7.
