Hello is it possible to color the data of a dataframe according to the values of one column? I have a dataframe that OI have subdivided into X and Y, with a third Z with the sample number. I would like to plot Y~X but coloring using Z. But I would like to use base R and not lines. Is that possible? Thank you
``` d <- 2 K <- 10^13 A1_0 <- 1 A2_0 <- 100 A3_0 <- 500 A4_0 <- 10000 PCR <- function(initCopy, dupRate, Carry) { ROI_T = initCopy A = array() for (i in 1:45) { ROI_TplusOne <- ROI_T * dupRate * (1 - ROI_T/Carry) A[i] <- ROI_TplusOne ROI_T <- ROI_TplusOne } return(A) } A1 <- PCR(A1_0, d, K) A2 <- PCR(A2_0, d, K) A3 <- PCR(A3_0, d, K) A4 <- PCR(A4_0, d, K) # store results and plot Z <- c(rep(1, 45), rep(2, 45), rep(3, 45), rep(4, 45)) X = rep(1:45,4) Y = c(A1, A2, A3, A4) ROI <- data.frame(Z, X, Y) plot(Y ~ X, data = ROI, type = "l", lwd = 3) ``` ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
