Dear Michael, my package has setOldClass("inla") and the NAMESPACE contains exportClasses(inla) and importFrom(INLA, inla.posterior.sample) the old version of INLA uses the S3 class "inla" but does not export it. the new version of INLA has setOldClass("inla") and the NAMESPACE contains exportClasses(inla) installing my package in combination with an older INLA

Just to clarify, your package is exporting a class that is not defined? Or is it exporting a class that is defined by a dependency and then masked by setOldClass()? A simple reproducible example would help.

Dear all, When running R CMD check on our package, we get an error on the examples. Error in grDevices::dev.off() : cannot shut down device 1 (the null device) None of the examples in our package generates plots. grDevices::dev.off() is code added by R CMD check. A workaround is to have at least one example which has some plot. Is there a better solution? We are using R 3.5.1 Best

Dear List, I'm trying to add a function that calls a Shiny App in my R package. The issue is that within my function, I'm creating objects that I'd like to pass to the app. For instance, from the example below, I'm getting "Error: object 'xs' not found". How can I pass "xs" explicitly to shinyApp()? *Under R directory:* myApp <- function(x, ...) {

Dear Massimo, It seems straightforward to use weighted.mean() in a dplyr context library(dplyr) mydf %>% group_by(date_time, type) %>% summarise(vel = weighted.mean(speed, n_vehicles)) Best regards, ir.

Dear Paula, There are probably missing observations in your data set. Read the na.action part of the glm help file. na.exclude is most likely what you are looking for. Best regards, ir.

Thierry, thanks for this, this is a bug in utils:::.format_person_as_R_code(). This calls deparse() on the elements of the person object with the default width.cutoff = 60. As your comment exceeds this width, the erroneous formatting is produced. The simplest reproducible example I could come up with was: p <- person(".", comment = c(foo = ".....................",

Dear Sacha, use glm() in this case. I'd rather code the covariable as TRUE / FALSE or as a factor. Best regards, ir.

Dear Laura, It looks like you want to remove all rows for which each column is NA. You can to that with the code below. na.matrix <- is.na(MyData) all.na.row <- apply(na.matrix, 1, all) MyData[!all.na.row, ] Best regards, ir.

You need to make sure that the rJava package is working. Consider using the readxl package instead of xlsx. Best regards, ir.
