How to assign something in a for loop?-CodePudding

Do you know how to assign these in a loop so it's less exhaustive?

number1 <- as.data.frame(do.call(cbind, my_list[1]))
number2 <- as.data.frame(do.call(cbind, my_list[2]))
number3 <- as.data.frame(do.call(cbind, my_list[3]))
number4 <- as.data.frame(do.call(cbind, my_list[4]))
number5 <- as.data.frame(do.call(cbind, my_list[5]))

I have tried:

for (i in 1:5) {
(number(i) <- as.data.frame(do.call(cbind, my_list[(i)])))
}

which doesn't work.

Any ideas?

If you want to extract all the elements of a list in a data frame, you can use assign:

# Example list with 5 elements
my_list <- list(1:5, 1:5, 1:5, 1:5, 1:5)

for(xx in seq_along(my_list)){
  assign(paste0("number", xx), as.data.frame(do.call(cbind, my_list[xx])))
}

This will create 5 data frames in your global environment named number1, number2, ..., number5

You can use assign() function to do that. Please use the following example to get the idea and edit your code:

number1 <- data.frame()
number2 <- data.frame()
number3 <- data.frame()
number4 <- data.frame()
number5 <- data.frame()

for (i in 1:5) {
  m <- data.frame(x=rnorm(10), y=rnorm(10))
  assign(paste0('number',i), m)
}
number1
number2
number3
number4
number5

Best of Luck.
