[R-pkg-devel] Warning 'as.data.frame.POSIXct()' is deprecated

[Vincent van Hees]

Thanks, in that case the REPLEX for the issue may need to be:

> remember = Sys.getenv("_R_CHECK_AS_DATA_FRAME_EXPLICIT_METHOD_")
> Sys.setenv("_R_CHECK_AS_DATA_FRAME_EXPLICIT_METHOD_" = TRUE)
> data.frame(time = Sys.time())
                 time
1 2023-07-06 14:29:37
> data.frame(time = as.POSIXlt(Sys.time()))
                 time
1 2023-07-06 14:29:37
Warning message:
Direct call of 'as.data.frame.POSIXct()' is deprecated.  Use
'as.data.frame.vector()' or 'as.data.frame()' instead
> Sys.setenv("_R_CHECK_AS_DATA_FRAME_EXPLICIT_METHOD_" = remember)
