Works in RStudio IDE but not in RStudio Cloud

[dsfernandez]

The following code, works perfectly in RStudio IDE but not in my RStudio Cloud project:

library(multcomp)
attach(cholesterol)
chol <- as.data.frame(cholesterol)
chol
detach(cholesterol)

visualizar por tratamiento (columnas)

library(tidyr)
library(dplyr)
tratamientos <- chol %>%
group_by(trt) %>%
mutate(n = row_number()) %>% # para crear valores únicos no lista
pivot_wider(names_from = trt,
values_from = response)

Here is the error:
Error: n() must only be used inside dplyr verbs.

Thanks,

Denny S.

Maybe your package versions are not the same in both places (a key aspect for reproducibility).

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

A link to your RStudio Cloud project (with access permissions) would be helpful too.

Thank you Andrés for your quick response. Here is the link to the RStudio Cloud project with the issue:

The name of the specific project is anova

solved: restarting R solved the situation in RStudio Cloud. Thanks
