Can you please help me ?

I am getting the error message

"Error in left_join(raw_data_2, mapping_file, by = "key_4") : could not find function "left_join".

I was able to run the same program few days back. I have uninstalled and installed R and R Studio both. But still it is not working.

Please help me..!

  • If you don't have `dplyr` installed. install it via `install.packages('dplyr')` and do `library(dplyr)` before using `left_join`. – Ronak Shah Apr 17 '20 at 09:51

    Use `library(dplyr)` if you already downloaded the package. – J_F Apr 17 '20 at 09:51
  • getting some weird error. after runiing the library(dplyr), Error: package or namespace load failed for ‘dplyr’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): namespace ‘vctrs’ 0.2.0 is being loaded, but >= 0.2.4 is required – avinash0513 Apr 17 '20 at 09:55

    Eventually update the packages **vctrs** and **dplyr** – jogo Apr 17 '20 at 10:25

Join functions are come with 'dplyr' package in R. This error occurs due to inactivate library 'dplyr'. You need to activate this library using library(dplyr) before your code. If it's not installed, first need to install using install.packages('dplyr').

#install.packages('dplyr')
library(dplyr)

#your code up to creating raw_data_2 and mapping_file
left_join(raw_data_2, mapping_file, by = "key_4")
