Dear list, I'm hoping the R guru's can help with an error i've been getting for at least a year during active package development. I have a package loaded & spot a documentation bug, so I: edit the Rd file (or in the roxygen header + roxygenize); then R CMD BUILD, R CMD INSTALL then in the same R session, reload the library & lookup a man page, I always get this error: Error in fetch(key) : internal error -3 in R_decompress1 I've tried all ways of reloading the package that i'm aware of: detach then library unloadNamespace then library devtools::install devtools::reload all lead to the error. I see from ?detach: ... So detaching and re-attaching a package may not refresh some or all components of the package, and is inadvisable. restarting the R session results in loading the updated man file, but do you have any ideas how to word around this & continue within the same R session? cheers, Mark # 1) using Hadley's devtools
library(devtools)
library(updateR) # my package under development
install("~/src/R/updateR")
To avoid this problem, the latest version of devtools has show_rd(), which allows you to preview an Rd file in R without having to reinstall the package. This was actually really simple to implement, and I don't know why I didn't think of it ages ago - it's certainly made my workflow much smoother. Hadley
