In R, I currently have 100 dataframes, named df.1
, ..., df.100
. I would like to be able to rbind
them but it is costly to write out:
rbind(df.1, df.2, etc)
So, I have tried:
rbind(eval(as.symbol(paste0("df.",1:84, collapse = ", "))))
However, this returns errors. Does anyone know how I can make the dataframes usable? thanks.
You can rbind
them one at a time in a loop.
df.1 = iris
df.2 = iris
df.3 = iris
DF = df.1
for(i in 2:3) {
DF = rbind(DF, eval(as.symbol(paste("df", i, sep=".")))) }
Using mget
and then do.call
or dplyr
's bind_rows
should work.
df.1 = iris[1:20,]
df.2 = iris[21:50,]
do.call("rbind",mget(paste0("df.",1:2)))
library(dplyr)
bind_rows(mget(paste0("df.",1:2)))
