Error: `quantile.haven_labelled()` not implemented.

Today I got an Error: `quantile.haven_labelled()` not implemented on a database imported into R via library(haven) when trying to see the results of a simple linear regression model. What I needed was the zap_labels() function, which strips the value labels (and user-defined NA). Then I run the model on the new dataset, and all was good.

dataset2 = zap_labels(dataset)

R-Forge: File ‘/pkg/DESCRIPTION’ is out of date

I came across a puzzling “File ‘/pkg/DESCRIPTION’ is out of date” error when updating an R-package of mine on R-Forge today. I was pretty sure the version number and date were correct. I couldn’t figure out any other issue, so I made a copy of my documents, checked out the code again, and copied the modified files back. All worked. I’m still a bit puzzled as I only use one machine for this, but who cares if the code is working…

pandoc-citeproc: “stdin” (line 31, column 2): unexpected “b”

Today I came across the following error in pandox (pandoc-citeproc) that was a bit cryptic to me:

pandoc-citeproc: "stdin" (line 31, column 2): unexpected "b"
expecting "c", "C", "p", "P", "s" or "S"
[...]

When I also got this on an empty text (markdown) file with just a reference in it, I realized that the markdown document was not the problem. Indeed, I had inadvertedly deleted a trailing comma in the bibtex document.

@article{lee
title = {Racial [...]

doesn’t work; it should be:

@article{lee,
title = {Racial [...]
