[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 ...
What could cause this?

Can you make the package source (incl that Rdata file) available? Best, Uwe Ligges

As to why: we need the reproducible example the posting guide asked you to provide.> 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 ... > > What could cause this? >-- Brian D.
