I have around 200 data frames I want to rbind in a vectorized way.
The object names are:
m302
m303
...
m500
So I tried:
mlist <- paste("m",302:500,sep="")
dat <- do.call("rbind", get(list(mlist)))
and I get "Error in get(x, envir, mode, inherits) : invalid first argument"
Yep. get() takes a single variable name as its argument.
If you tried get(list("m302","m303")) you would get the same error.
I know "rbind" is valid because
dat <- rbind(m302, m303, m304, m305)
works, I am just too lazy to type it out to m500.
I also tried it without the get() portion, but then dat ends up being
a column with just the names of the objects, not the objects
themselves.
Indeed. This translates to rbind("m302","m303"....
You could use mget() instead of get().
