How do I extract dataframe from a string?

Table1 <- read.csv("table1.csv", header = T, sep = ",")
Table2 <- read.csv("table2.csv", header = T, sep = ",")
Table3 <- read.csv("table3.csv", header = T, sep = ",")
Table4 <- read.csv("table4.csv", header = T, sep = ",")
tables <- c("Table1", "Table2", "Table3", "Table4")
tables
[1] "Table1" "Table2" "Table3" "Table4"
tables[2]
[1] "Table2"

Above are my codes. I wish to extract the data in "tables". For example, when I select tables[2], I wish to see the data in table2.csv instead of just the word "Table2". How do I do this? Can anyone please help? Thanks!

  • I think what you need might be something like below
get(tables[2])

which fetches object Table2 from your global environment

  • If you save all objects in to a list named tables, i.e., 
tables <- list(Table1, Table2, Table3, Table4)

then you can call tables[[2]]

Make a list of your tables if you really want:

tables <- list(Table1, Table2, Table3, Table4)

E.g. 

tables[[1]]

What you've done is make a vector of strings, where your strings are "Table1", "Table2" etc. rather than storing the table objects.
