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)
```

1. lines() *is* base R.
2. See the col argument of ?plot.default.

No. I was wrong. ?plot.default says only one line color (the first) will be
used. So it appears that you need to use lines().

Hello,
Base R:
colrs < rainbow(length(unique(ROI$Z)))
roi_wide < reshape(ROI, v.names = "Y", timevar = "Z", idvar = "X",
direction = "wide")
matplot(roi_wide, type = "l", lwd = 3, lty = "solid", col = colrs)
Hope this helps,
Rui Barradas

I did not know about matplot, but it did the work. using lines is my
default procedure but it can be timeconsuming. Thank you all.
