How to replace data in a data frame in R?
I am currently a novice in R (I have the basics, that's all), and I have a small issue in a data frame :

What I want to do here is :
- For all elements in the Wage column, replace the 'K' with '000'
- For all elements in the Value column : if the cell contains a '.', then replace the 'M' with '00000', if not, then replace it with '000000'
I guess this could by achieved with a for loop, but after trying I can say that I am not used to it.
Thanks for your answers,

Hi, please consider editing your question to add the output ofdput(head(dataframe,20))rather than an image. Also sample code of what you've tried is appreciated. Cheers!

A solution similar to this is probably more comprehensive:
parseBigNumbers <- function(vec) {
vec <- gsub("K", "e+3", vec)
vec <- gsub("M", "e+6", vec)
as.numeric(substr(vec, 2, nchar(vec)))
}
df$Wage <- parseBigNumbers(df$Wage)
df$Value <- parseBigNumbers(df$Value)
Thank you, this worked too ! I might go for this solution because I might have other columns where I need to use this method. Thanks !
