R - loop through multiple dataframes from a list of names

Question

I have a number of large DFs and I want to loop through them. Instead of binding them together to make a big list I thought I should make a simple vector with their names an

Answer 1

In your own code, just replace print(nrow(i)) with print(nrow(get(i))), since i is: chr "DF1" etc.

for (i in MyDFs) {
     print(nrow(get(i)))
}
[1] 3
[1] 3
[1] 3

Answer 2

Or

 sapply(mget(MyDFs),nrow)
 #DF1 DF2 DF3 
 # 3   3   3 

If you don't want to create a vector MyDFs

 sapply(mget(ls(pattern="DF")), nrow) #should also work
