[R-meta] Error - assigned vs existing data

[John Tully]

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. ℹ 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.

This follows the commands

for (region in regions){
  for (study in unique(df$studyid)){
    single_study_df <- df %>% filter(studyid==study)
    if (is.na(single_study_df[sprintf('%s_mn', region)][[1]]) & !is.na(single_study_df[sprintf('%s_mn_l', region)])){
      df <- calc_bilat(study, region, r, df)
    }
  }
}


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.

I would greatly value your input on this matter

Kind regards

John Tully
