Apologies if this question is too easy, I know how to do it in Python but I currently need it in R.

As part of an SQL query I get a variable with some numbers (the length can vary), as a string, like so:

`x <- "{0.5,0.25,0.75,0.5}" `

I can get rid of the brackets and commas, thus:

`library(stringr) library(dplyr) y <- x %>% str_remove_all("[{]") %>% str_remove_all("[}]") %>% strsplit(",") `

...but the output which I receive is still a list of strings:

`> y [[1]] [1] "0.5" "0.25" "0.75" "0.5" `

How do I make sure y is always a list of numbers?

You can do this in base R as

`as.numeric(strsplit(substr(x, 2, nchar(x) - 1), ',')[[1]]) `

or

`as.numeric(strsplit(gsub('[{]|[}]', '', x), ',')[[1]]) `
