date_lines

A character(2) vector with the start and end text lines used for detecting the start and end times of the job.

## Example log file
bsp2_log <- system.file("extdata", "logs", "delete_bsp2.txt", package = "sgejobs")

## Find start/end dates
log_date(bsp2_log)
#>                     start                       end 
#> "2019-09-07 14:40:21 EST" "2019-09-07 14:40:59 EST" 

## Another example log file
twas_gene_HIPPO <- system.file("extdata", "logs",
    "compute_weights_full_HIPPO_gene.1.txt",
    package = "sgejobs"
)
log_date(twas_gene_HIPPO)
#>                     start                       end 
#> "2019-08-12 16:35:41 EST" "2019-08-12 16:35:46 EST"
