I have three data frames: df1, df2, df3.
I want to merge them into a list:
dataframes <- list(df1, df2, df3)
How can I use the names of each data frame for their corresponding list element names?
So that instead of this:
> names(dataframes)
[1] "" "" ""
I get this:
> names(dataframes)
[1] "df1" "df2" "df3"
You need to name them when creating the list:
dataframes <- list(df1=df1, df2=df2, df3=df3)
names(dataframes)
#"df1" "df2" "df3"
Here is one option using a loop. I assume that df1, df2, and df3 are data frames, and have been defined somewhere.
i <- 1
lst <- list() # an empty list
while (i <= 3) {
df_name <- paste0("df", i)
lst[[i]] <- get(df_name)
names(lst)[i] <- df_name
i <- i + 1
}
names(lst)
[1] "df1" "df2" "df3"
While many view using loops in R as being evil, the above case is not so bad, because we simply add new list items (and their names) one by one, as the loop progresses.
