I found out that there is function called .hex.to.dec in the fBasics package.
When I do .hex.to.dec(a), it works.
I have a data frame with a column samp_column consisting of such values:
a373, 115c6, a373, 115c6, 176b3 When I do .hex.to.dec(samp_column), I get this error:
"Error in nchar(b) : 'nchar()' requires a character vector"
When I do .hex.to.dec(as.character(samp_column)), I get this error:
"Error in rep(base.out, 1 + ceiling(log(max(number), base = base.out))) : invalid 'times' argument"
What would be the best way of doing this?

Hex numbers are read the same way, but each digit counts power of 16 instead of power of 10. For hex number with n digits: d n-1 ... Multiply each digit of the hex number with its corresponding power of 16 and sum: decimal = d n-1×16 n-1 + ...

If we want to format the decimal places of one specific number (or a vector of numbers), we can use the format function in combination with the round function and the specification nsmall. Consider the following R syntax: format ( round ( x, 3), nsmall = 3) # Apply format function # "10.766".
Hex numbers are read the same way, but each digit counts power of 16 instead of power of 10. For hex number with n digits: d n-1 ... d 3 d 2 d 1 d 0. Multiply each digit of the hex number with its corresponding power of 16 and sum: decimal = d n-1×16 n-1 + ... + d 3×16 3 + d 2×16 2 + d 1×16 1+d 0×16 0.
Use base::strtoi to convert hexadecimal character vectors to integer:
strtoi(c("0xff", "077", "123")) #[1] 255 63 123 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" If you love us?
