How to name a new dataframe based on input character value

Question

In R, I am trying to get input from a user to create the name of a new data frame. eg

number <- readline(prompt = "what is your number:")

Which creates a character string with one entry, eg number: "4"

Now i want to create a dataframe named after the character inputted, and subset some other information based on that number from another table, for example:

number_4 <- subset(df, df$NO=="4")

As i might be doing hundreds of these i do not want to have to manually name each dataframe, is there a way to use the character to name a dataframe?

Answer 1

我们可以使用assign功能

assign(paste0("number_", number), subset(df, NO == number))
