I'm trying to combine multiple dataframes into one dataframe using bind_rows. Each dataframe has the same column names and length. Let's say each dataframe is named "df" and there are 100 of them. So df1, df2, df3... df100.
I do not want to write each dataframe in the function as bind_rows(df1, df2 ... df100). I tried
total_df <- bind_rows(paste0(df1:df100))
It did not work. Would there be an easier way to do this? Thank you!!

bind_rows() function in R Programming is used to combine rows of two data frames.
Syntax of the rbind() function rbind(): The rbind or the row bind function is used to bind or combine the multiple group of rows together.
cbind() and rbind() both create matrices by combining several vectors of the same length. cbind() combines vectors as columns, while rbind() combines them as rows.
The name of the rbind R function stands for row-bind. The rbind function can be used to combine several vectors, matrices and/or data frames by rows. Above, you can find the basic code for rbind in R.
The cbind () function combines R Objects By Rows Or Columns. To bind or combine rows in R, use the rbind () function. The rbind () stands for row binding. The rbind () function can combine various vectors, matrices, and/or data frames by rows. In short, to join two data frames (datasets) vertically, use the rbind () function.
bind_rows () function in R Programming is used to combine rows of two data frames. Here in the above code, we created 3 data frames data1, data2, data3 with rows and columns in it and then we use bind_rows () function to combine the rows that were present in the data frame.
In other words, Rbind in R appends or combines vector, matrix or data frame by rows. bind_rows () function in dplyr package of R is also performs the row bind opearion. lets see an example of both the functions. In this Tutorial we will look at Example of row bind operation in R by using rbind () function.

The easier way would be to avoid having a bunch of dataframes named df1, ..., df100 from the start by making use of a list. Be that as it may. You could make use of lapply and get to put your df's into a list and call bind_rows on the list:
library(dplyr)
df1 <- mtcars
df2 <- mtcars
df3 <- mtcars
df_bind <- lapply(1:3, function(x) get(paste0("df", x))) %>%
bind_rows()
head(df_bind)

or using mget you could do
mget(paste0("df", 1:3)) %>% bind_rows()
