unused arguments error occurs in response

Question

Upon runing this code,

Attrition_edufield <- myds %>%
select(Attrition, EducationField) %>%
group_by(Attrition, EducationField) %>%
summarize(count = n())

I get response with

Error in select(., Attrition, EducationField) : unused arguments (Attrition, EducationField)

Any idea why this occurs?

You are trying to use dplyr's select; however it appears that you have loaded another package that also defines a select function after loading dplyr and thus masking the one from dplyr.

Restart your R session, and load all the packages you use, while keeping an eye out for messages.

Try specifying the namescope by calling

Attrition_edufield <- myds %>%
  dplyr::select(Attrition, EducationField) %>%  # that's dplyr with two colons in front
  group_by(Attrition, EducationField) %>%
  summarize(count = n())

As an alternative, check that your variable myds is a data.frame (or related structure) and contains the columns you are trying to select.

Some packages 'mask' certain objects from other packages. For instance if you call library(dplyr) then library(clusterSim) you'll get a message: 'The following object is masked from ‘package:dplyr’: select'. There may be another way to get around it but at first you may want to run your dplyr commands and then call the other packages which mess with it.
