Is there a standard function in R to convert strings representing numbers of bytes such as
to integer numbers of bytes?
I came across humanReadable
in the package gdata, but this does the conversion the other way round. I know that I can parse the string and then do the maths myself, but I wondered whether something exists already.
A simple function to do this:
x <- c("11855276K", "113M", "2.40G", "1234")
convb <- function(x){
ptn <- "(\\d*(.\\d+)*)(.*)"
num <- as.numeric(sub(ptn, "\\1", x))
unit <- sub(ptn, "\\3", x)
unit[unit==""] <- "1"
mult <- c("1"=1, "K"=1024, "M"=1024^2, "G"=1024^3)
num * unname(mult[unit])
}
convb(x)
[1] 12139802624 118489088 2576980378 1234
You may want to add additional units and conversions, e.g. terabytes.
