[adegenet-forum] length of 'dimnames' [1] not equal to array extent

[Brian Simison]

I have tried to convert various format output by Stacks2 'populations'
script with no success. I have tried both structure and genepop formats and
continually get the cryptic error "length of 'dimnames' [1] not equal to
array extent"

In Rstudio in Win10 I run:
 >Trach <- read.genepop("populations.gen")

 Converting data from a Genepop .gen file to a genind object...

File description:  2_52, 2_53, 2_74, 4_15, 4_18, 4_39, 4_84, 5_17, 5_35,
5_61, 6_24, 6_49, 6_50, 6_88, ... (I deleted the middle of the file
description for space)

I have searched for this error and have failed to understand what
"Dimnames" are.

thank you in advance.
