How to coerce a list object to type 'double'

Question

The code:

a <- structure(list(`X$Days` = c(\"10\", \"38\", \"66\", \"101\", \"129\", \"185\", \"283\", 
                                 \"374\")), .Names

You can also use list subsetting to select the element you want to convert. It would be useful if your list had more than 1 element.

as.numeric(a[[1]])
