Comma separated numerical values as strings.

[Rtip] In my continuous series of 'Rtips', i came across this annoying set of numerical values that are expressed as strings with commas. for example "20,000,123" that should read as 20000123 . This is common when working with monetary sums or totals. So how would you convert that to readable numbers or integers. I found out that gsub function really good at refomatting this character vector. 

       

> budgets_amounts <- c("20,929,200","782,000,000","100,000,000","14,111,122") 
> as.numeric(gsub(",","", budgets_amount))
[1]  20929200 782000000   100000000 14111122
