Questions tagged [tidyverse]

ONLY use this tag if your question relates to the installation, integration with your system, or inclusion of the entire tidyverse library. DO NOT USE if your question relates to one or two components of the tidyverse, such as dplyr or ggplot2. Use *those* tags, and tag with `r` as well for a better response.

tidyverse is an R package that installs a number of other packages for data processing and graphics.

Unless your question is about the entirety of the tidyverse package, its installation or its integration with your system, use tags for the packages you are actually using. Using library(tidyverse) is rarely a minimal reproducible example when only library(dplyr) is required.

See https://www.tidyverse.org/packages/ for a breakdown of the packages contained in tidyverse and their respective functions.

Tidy evaluation when column names are stored in strings

I need to filter a table by a logical column (or, more precisely, by its negation), but the name of the column may vary. It's easy when I know their names beforehand: tb = tibble( id = 1:4, col1 = c(TRUE, TRUE, FALSE, FALSE), col2 = c(TRUE,…
