[R] weird error with a lazyload .RData file in a package
I added a new data file, NLSY.RData, to a package that uses LazyData: Yes It passed R CRAN check and R CMD install worked w/o significant complaints. * installing to library 'C:/R/R-2.15.2/library' * installing *source* package 'heplots' ... ** R ** data ** moving datasets to lazyload DB ** demo ** inst ** preparing package for lazy loading Warning: package 'nnet' was built under R version 2.15.3 ** help ... Yet, when I try to use it, I get something incomprehensible: library(heplots) str(NLSY) Error in str(NLSY) : internal error -3 in R_decompress1 In addition: Warning message: In str(NLSY) : restarting interrupted promise evaluation But it works if I load directly from the file I imported into the package: load(NLSY.RData) str(NLSY) 'data.frame': 243 obs. of 6 variables: $ math: num 50 28.6 50 32.1 21.4 ... $ read: num 45.2 28.6 53.6 34.5 22.6 ... $ antisoc : int 4 0 2 0 0 1 0 1 1 4 ... $ hyperact: int 3 0 2 2 2 0 1 4 3 5 ... $ income : num 52.52 42.6 50 6.08 7.41 ... $ educ: int 14 12 12 12 14 12 12 12 12 9 ...

As to why: we need the reproducible example the posting guide asked you to provide. I had the same symptom a couple of days ago. It went away after quitting and restarting the R session. I kind of put it down to leaving an R session running while updating R (Yeah, I know: Still nothing reproducible...). The warning about nnet from 2.15.3 while installing to R-2.15.2/library suggests that something similar could be afoot in this case. -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd@cbs.dk Priv: pda...@gmail.com __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
