Dear colleagues
>
> in conducting a meta-analysis (of MRI data) I am running into the repeated
issue:
>
> Error: Assigned data `single_study_df` must be compatible with existing
data. ? Error occurred for column `accumbens_sd`. x Can't convert from
<double> to <logical> due to loss of precision. * Locations: 1, 2.
Run `rlang::last_error()` to see where the error occurred.

>      if (is.na(single_study_df[sprintf('%s_mn', region)][[1]])
& !is.na(single_study_df[sprintf('%s_mn_l', region)])){

> My colleague (cc'd) believed it may be an issue with tidyverse version,
however using an older version (1.2.1), the issue persists. note
'accumbens' is the first of many columns so I suspect this is why it
flags this up.
