error when parsing pzfx with empty Y columns

[slyrus]

I see the following error parsing one of my pzfx files:

> pzfx::read_pzfx(ap_data_pzfx_file, "FOO", strike_action = "exclude")
Error in names(x) <- value : 
  'names' attribute [3] must be the same length as the vector [1]
> traceback()
4: `colnames<-`(`*tmp*`, value = col_names)
3: FUN(X[[i]], ...)
2: lapply(col_lst, function(c) {
       while (nrow(c) < max_len) {
           col_names <- colnames(c)
           c <- rbind(c, NA)
           colnames(c) <- col_names
       }
       c
   })
1: pzfx::read_pzfx(ap_data_pzfx_file, "FOO", strike_action = "exclude")

I notice that the offending regions of my file have the following XML:

<YColumn Width="162" Decimals="3" Subcolumns="3">

<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
</YColumn>
<YColumn Width="162" Decimals="3" Subcolumns="3">

<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
</YColumn>
<YColumn Width="162" Decimals="3" Subcolumns="3">

<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
</YColumn>
<YColumn Width="162" Decimals="3" Subcolumns="3">

<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
<Subcolumn></Subcolumn>
</YColumn>

If I delete these empty YColumn entries, the file parses fine.

Thanks for reporting, i think it's a bug introduced by not handling multiple empty sub columns carefully. Should be fixed in the current master branch - please feel free to reopen if not.
