Madison, by the way, it's sort of hard to follow your example. there's some concept of MWE ==? Minimum Working Example. duckduckgo, or others on the list, can probably point the way.
and, by the way :), i'm no expert. in particular, not on magrittr pipes, or on group_*, though i use both in some of my code. > data <- read_csv("data_raw/EpiTest.csv") %>% > group_by(TestAssay)%>% > group_map(~ epi_analysis) sans-pipe, i would have had : group_map(df, epi_analysis, the_dir) or some such. in magrittr pipes, maybe that would be : ... %>% group_map, epi_analysis, the_dir) or some such? hth. cheers, Greg ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
