Posted the below over on stackoverflow but have since found that 4.1.1 and 4.1.0 throw up fatal errors whereas 4.0.1 does not on the same system (64 bit Windows).
Is this something that R devs might know more about? Why is this error occurring on later versions?
I have two large named vectors and want to subset bar to give a vector that only includes those elements matching named elements in foo.
The data look like this:
# foo
> length(foo)
[1] 51174
> foo[1:10]
the to a you and of i is that in
25499 24985 23053 22064 20687 16042 15351 13776 13714 9995
> names(foo[1:10])
[1] "the" "to" "a" "you" "and" "of" "i" "is" "that" "in"
# bar
> length(bar)
[1] 3755242
> bar[1:10]
the of to and a in is that for i
16330164 9263180 8295547 8159378 6391771 5410076 3585765 3531807 2881175 2465688
> names(bar[1:10])
[1] "the" "of" "to" "and" "a" "in" "is" "that" "for" "i"
To subset, I have previously used the following method without issue on the same data:
bar[names(foo)]
However, using this same method, I am now receiving an "R Session Aborted R encountered a fatal error" message unpredictably. Sometimes it works, sometimes it doesn't. How do I avoid causing a fatal error? Is this a memory issue?
