title: How to read data frame name from a csv and use it in a loop in R
body: <p>I  have created some 500 data frames in the global environment of R studio and I have the list of all these data frame names in a csv file. I need to collect the no. of observations of each data frames. I know I need to use the nrow(dataset_name) command but is there any way, I can create a loop such that R reads the dataset names from the csv and executes the nrow command?</p>
  
  <p>p.s.- I am a newbie to R, so plz pardon me if this question is very basic.
  TIA!</p>
