Suppose I have this vector

Is there a neat package to convert RGB values to hex values in R? I fo

Answer 1

You could use the sprint function in R and the hints in the following post: How to display hexadecimal numbers in C?

Answer 2

Just split the string up, and then use rgb:

x <- c("165 239 210", "111 45 93")
sapply(strsplit(x, " "), function(x)
    rgb(x[1], x[2], x[3], maxColorValue=255))
#[1] "#A5EFD2" "#6F2D5D"

Answer 3

You can convert to a numeric matrix and use colourvalues::convert_colours()

colourvalues::convert_colours( 
  matrix( as.numeric( unlist( strsplit(x, " ") ) ) , ncol = 3, byrow = T)
)
# [1] "#A5EFD2" "#6F2D5D"
