How can I do the same thing to multiple data sets?

Answer 1

One option is using a for loop. This way you can reiterate the same functions over multiple datasets. Another is doing something along the lines of the following:

Say you have Table1 and Table2 and want to make histograms of each table. You can do something like this:

dat <- table1

names(dat)

table(dat)

hist(dat)

Then if you want to run these commands on table2, you can just change the first like to dat <- table2.
