Convert hex to decimal in R
There is a simple and generic way to convert hex <-> other formats using "C/C++ way":
V <- c(0xa373, 0x115c6, 0xa373, 0x115c6, 0x176b3)sprintf("%d", V)#[1] "41843" "71110" "41843" "71110" "95923"sprintf("%.2f", V)#[1] "41843.00" "71110.00" "41843.00" "71110.00" "95923.00"sprintf("%x", V)#[1] "a373" "115c6" "a373" "115c6" "176b3"
As mentioned in @user4221472's answer, strtoi() overflows with integers larger than 2^31.
The simplest way around that is to use as.numeric().
V <- c(0xa373, 0x115c6, 0x176b3, 0x25cf40000)as.numeric(V)#[1] 41843 71110 95923 10149429248
