This change in R-devel just bit me. Under the newest release, if I attach() another .RData directory, the methods are not detected. Was it intentional? Running in Linux. Here is a script of an example that works fine under 3.6.2. but fails in R-devel.
tmt% mkdir temp1 tmt% cd temp1 tmt% R # define a silly method, just for testing charlie <- function(x, ...) UseMethod("charlie") charlie.default <- function(x, ...) { cat("default method ", x, "\n") x +2 } charlie.character <- function(x, ...) { cat("character method ", x, "\n") as.character(as.numeric(x) + 2) } > quit("yes") tmt% cd .. tmt% R > attach("temp1/.RData") > charlie( 4) Error in UseMethod("charlie") : no applicable method for 'charlie' applied to an object of class "c('double', 'numeric')" ---------------------------------------- The use case was my local test environment for the survival package. I can work around it. -- Terry M Therneau, PhD Department of Health Science Research Mayo Clinic thern...@mayo.edu "TERR-ree THUR-noh" [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
