DISCLAIMER: I can not get this error with R --vanilla, so it only
occurs when some other package is also loaded. I don't have time to
find to narrow that down for a reproducible example, but I believe the
following error in R 3.6.0:
> Sys.setenv("_R_CHECK_LENGTH_1_LOGIC2_" = "true")
> library(oligo)
Error in omittedSig && (signature[omittedSig] != "missing") :
'length(x) = 4 > 1' in coercion to 'logical(1)'
Error: unable to load R code in package 'oligo'
is because of a '_R_CHECK_LENGTH_1_LOGIC2_=true' mistake in the
'methods' package. Here's the patch:
$ svn diff src/library/methods/R/RMethodUtils.R &

Maybe still in time for R 3.6.1?
