I just began to learn R. I am trying to use the dplyr package to manipulate data. While using the select function, this is the error that pops up.

dplyr::select(flights, DepTime, ArrTime, FlightNum)

Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : there is no package called ‘rlang’

I'm really lost and have no idea how to proceed. Any insight would be much appreciated. I have installed and called the dplyr library. Still, none of the dplyr functions seem to be working.

    either re-install `dplyr` with dependencies, e.g. `install.packages("dplyr",dependencies=TRUE)` or just install the dependent package by itself with `install.packages("rlang")` then do `library(dplyr)` again -- sometimes this happens when a CRAN repository has a (usually temporarily) corrupt package and you download it – mysteRious Jun 01 '18 at 22:19

    Also make sure that you restart your R session – Tung Jun 01 '18 at 22:30
