In mikejacktzen/datzen:

iterload: The iterload() function to easily read in .rds files

Description

The .rds files are expected to be output from from itersave This is essentially using lapply(list.files(dir_rds),FUN=readRDS)

Usage

iterload(dir_rds)

Arguments

Argument |Description ------------- |---------------- dir_rds | character for path of directory containing .rds files

Value

a list storing read in results

Seealso

itersave to see how the .rds files were written

Examples

```r

foo_func_spec = function(x){return(log(x))} mainDir = '~/projects/datzen/tests/proto/temp/' subDir = '/dump_1/' subSubDir = '/failed/'

######################## # error control ########################

arg_vec_spec = c(letters) names(arg_vec_spec) = stringr::str_sub(arg_vec_spec,start=-6) itersave(func_user=foo_func_spec,vec_arg_func=arg_vec_spec, mainDir,subDir,subSubDir='/failed/',parallel=FALSE) dir_rds_failed = '~/projects/datzen/tests/proto/temp/dump_1/failed/' list.files(dir_rds_failed) out_failed = iterload(dir_rds=dir_rds_failed) str(out_failed)

purrr::transpose(out_failed)$ind_fail purrr::transpose(out_failed)$input_bad purrr::transpose(out_failed)$result_bad

######################## # retrying itersave() on failed runs from 'input_bad' ########################

# NOTE: re-assemble named vector for arg_retry arg_bad = unlist(transpose(out_failed)$input_bad) # convert letters to its order in alphabet arg_retry = seq_along(letters) names(arg_retry) = stringr::str_sub(arg_bad,start=-6)

itersave(func_user=foo_func_spec,vec_arg_func=arg_retry, mainDir,subDir,subSubDir='/failed/',parallel=FALSE)

dir_retry = '~/projects/datzen/tests/proto/temp///dump_1/' out_failed = iterload(dir_rds=dir_retry) str(out_failed) ```
