state1 <- CA state2 <- IL state3 <- FL CA, IL, and FL are

  • 0
state1 <- "CA"
state2 <- "IL"
state3 <- "FL"

CA, IL, and FL are three data frames.
How to write a loop to remove these data frames using paste(“state”, i) where i is an integer? Assume there are many such data frames so that removing them one by one would be inefficient.

    if you have names of the dataframes in character vector say states then you can use
    rm(list=states)

    Now there are various ways of getting states

    Just create it and update it when a new state variable is created.
    e.g.

    CA <- data.frame()
states <- "CA"

IL <- data.frame()
states <- c(states, "IL")

FL <- data.frame()
states <- c(states, "FL")

    Or

    If you have names of object in variables like state1, state2 etc.. then you can do what David suggested

    states = sapply(paste("state", 1:2, sep=""), get)
rm(list = states)
