Can't convert `y` <character> to match type of `x`

[temospena]

Hi,

Thank you for this pkg.

I am trying to read a mbox file (from google takeout) and I am having this error:

data <- read_mbox(file)

Error in `dplyr::na_if()`:
! Can't convert `y` <character> to match type of `x` <tbl_df>.
Run `rlang::last_trace()` to see where the error occurred.

Any clue?
Thanks!

Thanks for reaching out. It's been a while since this package was not actively maintained, so I will need to revisit the codebase later to further investigate. Regrettably, I am not able to take a look in a short period of time. I will keep this open for my future investigation.

hi , thanks for the package, ❤️ ⭐

i'm having the same issue using the sample test code.

test code:

library(mboxr)
# Importing your mbox file into an R:
test <- system.file("extdata", "test1.mbox", package = "mboxr")
data <- mboxr::read_mbox(test)
data
 

error:

Error in `dplyr::na_if()`:
! Can't convert `y` <character> to match type of `x` <tbl_df>.
Backtrace:
 1. mboxr::read_mbox(test)
 4. dplyr::na_if(...)

I am encountering the same problem. I looked into the code for the key function, and the problem seems to be on line 26:

  df <- reticulate::import_from_path(module = "mboxR", path = system.file("python", 
                                                                          package = "mboxr"), convert = TRUE)$mbox_df(mbox)

This produces a tibble output of 0 rows.

@jooyoungseo I think this is probably a simple fix -- might you have time to take a look? This package is a dependency in a replication file of mine and I can't finalize it until I can get this dependency fixed!

Apologies for the delayed response. This package is no longer maintained and has been removed from CRAN. The last update was over five years ago, and a full redesign would be needed to make it stable.

I’m sorry for any inconvenience this has caused. I’ll add a deprecation note to README to clarify.

I recommend using {tm.plugin.mail} package as an alternative.
