Error in dplyr::mutate(): ℹ In argument: svm = ...[].

Hi! I have been excited to start exploring your package, however, unfortunately, my experience with working with it was a bit controversial. After some hours I could fix some implicit data requirements, but I still had some troubles with running auto_MrP. Every time I run the full model I receive this error (however, when using only pcm = TRUE the error is not shown) :

Error in `dplyr::mutate()`:
ℹ In argument: `svm = ...[]`.
Caused by error in `matrix()`:
! length of 'dimnames' [2] not equal to array extent
Run `rlang::last_trace()` to see where the error occurred.

This is my model:

mrp_auro_out<- auto_MrP(y = "usa_bad", 
                   L1.x= c("educ","sex", 'urban_rural', 'age',
                           'int1', 'int2', 'int3',
                           'int4', 'int5', 'int6'
                           ), 
                   L2.x= c('latitude', 'longitude', 'gdp_pc_98',  'russians_89_share', 'popul_tot',
                           'republic','capitals', 'mms'), 
                   L2.unit = "regions_89", 
                   L2.reg = "district", 
                   bin.size= "n", 
                   survey = geo_r1_rand_AUTOMRP[c(common_covs, "district", "regions_89", "usa_bad")],
                   census = ps_c1_AUTOMRP[c(common_covs, "district", "regions_89", "n")], 
                   cores = 8)

I am just interested what this error can refer to: problem with model convergence, wrong data properties or it is just a bug? Thanks in advance!

Hi,

I think this has to do with the dataset or is a bug. Can you share a part of your data to test this?
