Tiago,
Looking at https://www.stats.ox.ac.uk/pub/bdr/noSuggests/pliman.out we see it errors after trying '* checking examples ...': * checking examples ... ERROR Running examples in ‘pliman-Ex.R’ failed The error most likely occurred in: > ### Name: as_image > ### Title: Create an 'Image' object > ### Aliases: as_image > > ### ** Examples > > img <- + as_image(rnorm(150 * 150 * 3), + dim = c(150, 150, 3), + colormode = 'Color') Error in loadNamespace(x) : there is no package called ‘EBImage’ Calls: as_image ... loadNamespace -> withRestarts -> withOneRestart -> doWithOneRestart Execution halted * checking PDF version of manual ... [12s/12s] OK Looking at as_image.Rd in https://github.com/NEPEM-UFSC/pliman/blob/24a1781073f9b1a3141002f0985b0542b1f7178d/man/as_image.Rd we see that you do have an \donttest{} there but that alone does not protect you. Instead of \examples{ \donttest{ library(pliman) img <- as_image(rnorm(150 * 150 * 3), dim = c(150, 150, 3), colormode = 'Color') plot(img) } I would do something like if (interactive() && requireNamespace("EBImage", quietly=TRUE)) { library(pliman) img <- as_image(rnorm(150 * 150 * 3), dim = c(150, 150, 3), colormode = 'Color') plot(img) } where you could of course put that condition into a helper function.
