Dplyr select() returning error about labs HOT 2 CLOSED

Thanks for the quick reply. Appreciated.

I read on this forum that re-installing dplyr would help. I also made sure that dplyr was loaded after MASS.

For any other person experiencing this issue run these commands before doing a dplyr select:

detach("package:dplyr", unload=TRUE)
install.packages("dplyr")
detach("package:MASS", unload=TRUE)
library(MASS)
library(dplyr)

from labs.

I cannot reproduce your problem. Please check carefully.

Hi all,

Running the following code causes an error:
Error i select(., Bodyweight) : unused argument (Bodyweight)

Here is the full code:

library(rafalib)
library(downloader)
library(devtools)
library(dplyr)

install_github("genomicsclass/dagdata")
dir <- system.file(package="dagdata")
filename <- file.path(dir,"extdata/mice_pheno.csv")
dat <- read.csv(filename)

controlPopulation <- filter(dat,Sex == "F" & Diet == "chow") %>% select(Bodyweight) %>% unlist

I am running the following R installation through RStudio:

I attach a screenshot from RStudio too.
