As a newer R practicioner, it seems I stump myself weekly (at least) with
issues that have spinning my wheels. Here is yet another... I'm trying to turn
a list of numeric vectors (of uneual length) inot a dataframe. Each vector
held in the list represents a row, and there are some rows of unequal length.
I would like NAs as placeholders for "missing" data in the shorter vectors. I
think I'm missing something quite basic.
v1 <- c(1,2,3,4)
v2 <- c(1,2)
lst1 <- list(v1,v2)
Of course there is the intuitive:
as.data.frame(lst1)
However, the recycling rule (expectedly) reclycles 1,2 versus using NAs as
placeholders.
Then, looking into Teetor's R Cookbook, there is a piece of code that looked
(from the description) like it might do the trick:
do.call(rbind, Map(as.data.frame,lst1)
But I get the error:
Error in match.names(clabs, names(xi)) :
names do not match previous names
Thinking the source of the error had to do with the vectors of unequal lenght,
I tried Hadley's rbind.fill thusly:
library(reshape)
do.call(rbind.fill, Map(as.data.frame,lst1)
Which produced a dataset, but gain, not in the desired format.
Thanks in advance to anyone that can bring my frustrations to end!
