dagitty library : NULL response
Hello,
You have spaces in the method = " holm " argument. Remove them and have
the error function return the error to see the error.
tryCatch ({
r <- localTests(g1, d)
p.dagitty.param.correct <- min(p.adjust(r$p.value , method = " holm "))
}, error = function(e) {e})
#<simpleError in match.arg(method): 'arg' should be one of ?holm?,
#?hochberg?, ?hommel?, ?bonferroni?, ?BH?, ?BY?, ?fdr?, ?none?>
tryCatch ({
r <- localTests(g1, d)
p.dagitty.param.correct <- min(p.adjust(r$p.value , method = "holm"))
}, error = function(e) {e})
#Warning message:
#In min(p.adjust(r$p.value, method = "holm")) :
# no non-missing arguments to min; returning Inf
p.dagitty.param.correct
#[1] Inf
Hope this helps,
Rui Barradas

Dear R-experts,
Here below my R code (toy example). No message error but I would like to know why I get NULL as a response and what does it mean ?
Many thanks.
