Why do I get an error when trying to use names_glue in tidyr::pivot_wider?

Question

I get an unused argument error when trying to use the names_glue argument in tidyr::pivot_wider . Here's the example from the help page and my error:

library(tidyr)
us_rent_income %>%
  pivot_wider(
    names_from = variable,
    names_glue = "{variable}_{.value}",
    values_from = c(estimate, moe)
  )
Error in pivot_wider(., names_from = variable, names_glue = "{variable}_{.value}",  :
  unused argument (names_glue = "{variable}_{.value}")

I updated tidyr and glue .

I should note that without the names_glue argument, works just fine:

us_rent_income %>%
  pivot_wider(
    names_from = variable,
    names_sep = ".",
    values_from = c(estimate, moe)
  )

Answer 1

According to the changelog, it looks like pivot_wider() gained the names_glue argument in version 1.1.0. You're showing 1.0.2, right? Package 'tidyr' version 1.1.0 -also- Hadley's tidyr 1.1.0 blog announcement

This should solve your problem:

install.packages("tidyr")
library(tidyr)
us_rent_income %>%
  pivot_wider(
    names_from = variable,
    names_glue = "{variable}_{.value}",
    values_from = c(estimate, moe)
  )

Note, you may also have to update the vctrs package as well to version 0.3.0.
