Hello there,
with the following dummy code I'd like to give you an idea how my data
looks like:
df1 <- data.frame(a = rnorm(10), b = rnorm(10))
df2 <- data.frame(a = rnorm(10), c = rnorm(10))
df3 <- data.frame(a = rnorm(10), b = rnorm(10), c = rnorm(10))
myList <- list(df1, df2, df3) # (myList is representing the data
structure I have to handle, it's read from single files with lapply)
In every list entry is a data.frame but the columns are only partially
the same. If I have exactly the same columns, I could do the following
command to combine my data:
do.call("rbind", myList)
but of course it does not work with differnt column names. Is there any
easy way to retrieve a combined table like this:
a b c

30 -0.62615365 0.7330671 -0.4032405
The only thing I can think about is checking the names of each list
entry and adding NA-columns before combining them.
Is there any other way to do so?
