Remove names and more from list with capture.output()
Thanks David - this is pretty close to what I am looking for. However, the output of vec[2] now includes the row number [1] and quotations marks at the endpoints of the row. Is there an easy way to exclude those? Thanks Sverre

Hi R users, I end up with a list object after running an anova:
lm(speed ~ 1 + dist + speed:dist, data = cars) -> Int
lm(speed ~ 1 + dist, data = cars) -> NoInt
anova(Int, NoInt) -> test
test <- test[c("Df", "F", "Pr(>F)")][2,]
is.list(test)
[1] TRUE
test
?Df ? ? ?F ? ?Pr(>F) 2 -1 18.512 8.481e-05 *** --- Signif. codes: ?0 ?***? 0.001 ?**? 0.01 ?*? 0.05 ?.? 0.1 ? ? 1 I would like to use capture.output() when writing this information to a text file, but I would like to only print the row, not the names (Df ? ?F ? ?Pr(>F)), and not the significance codes. That is, I want the text printed to my text file to be: 2 -1 18.512 8.481e-05 ***
the output of capture.output is just going to be a character vector and you should select the second element.
vec <- capture.output(test) vec[2]
[1] "2 -1 18.512 8.481e-05 ***"
Is there a way to do this? Thanks Sverre
