Problem including a large matrix when using devtools install

[Philip Carter]

Hi,

I'm trying to use devtools install with a package that I am developing. I do the following after starting R:

library("devtools")                              

library("roxygen2")                               

setwd("./")                                       

install("myPackage")

But I get the error:

*** moving datasets to lazyload DB

Error in lazyLoadDBinsertVariable(vars[i], from, datafile, ascii, compress,  : 

  long vectors not supported yet: connections.c:5984

ERROR: lazydata failed for package ‘myPackage’

* removing ‘/home/phil/R/x86_64-pc-linux-gnu-library/3.6/myPackage’

* restoring previous ‘/home/phil/R/x86_64-pc-linux-gnu-library/3.6/myPackage’

Error in (function (command = NULL, args = character(), error_on_status = TRUE,  : 

  System command 'R' failed, exit status: 1, stdout & stderr were printed

I think this is caused by a recent addition of a large matrix in the myPackage data/ directory stored as largeMatrix.RData. If I remove that file, the install works fine again. I can load the matrix inside R, although it's big (matrix is 45000x24717).

I've looked at the devtools install documentation, but I didn't see anything like a parameter that I can set.

When I searched for a solution online, I saw some answers for similar problems where cache.lazy = FALSE was recommended for lazyLoadDBinsertVariable, but I'm not sure how to utilise this when working with someone else's package. If of course that is the problem, which I am not sure of.

Thanks very much in advance,

Phil
