### [R] Superscript and subscrib R for legend x-axis and y-axis and colour different subjects in longitudinal data with different colours

I am trying to make a x-axis and y-axis titles with both a special character and a subscript. I am not being able to do this. I think its just a placing of my parenthesis, but I've tried (seemingly) everything. Even more, when I try the blog users code it works. Is it because I?m using longitudinal data? Even more. Is it possible to colour each one of the 15 lines with a different colour? library(ggplot2) library(reshape) library(lattice) library(gtable) library(grid) attach(mtcars) beta0 = rnorm (15, 1, .5) beta1 = rnorm (15, -1, .5) tempo = seq(1:5) CRP7raw = matrix(NA, 15, 5) CRP7 = matrix(NA, 15, 5) CRP98raw = matrix(NA, 15, 5) CRP98 = matrix(NA, 15, 5) crp <- for (i in 1:15) { CRP7raw[i,] = beta0[i] + beta1[i] * tempo CRP7[i,] = CRP7raw[i,] + rnorm(5, 0, 2.14) CRP98raw[i,] = beta0[i] + beta1[i] * tempo CRP98[i,] = CRP98raw[i,] + rnorm(5, 0, .1) } # plot(c(1:5), CRP7raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5) , # xlab="Day in ICU", # ylab="CRP (mg/dL)", # sub = mtext(expression(paste(lambda))) # # CRP7graph <- apply(CRP7, 1, lines, col="gray") # plot(c(1:5), CRP98raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5), # xlab="Day in ICU", # ylab="CRP (mg/dL)") # CRP98graph <- apply(CRP98, 1, lines, col="gray") par(mfrow=c(1,2)) plot(c(1:5), CRP7raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5) , xlab="t_i", ylab="y_ij", sub = "lambda = 0.7") CRP7graph <- apply(CRP7, 1, lines, col="gray") plot(c(1:5), CRP98raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5), xlab="Day in ICU", ylab="CRP (mg/dL", sub = "lambda = 0.98") CRP98graph <- apply(CRP98, 1, lines, col="gray") [[alternative HTML version deleted]]

1. Why all the library calls to ggplot and lattice if you are using only basic graphics? 2. Note that: sub = mtext(expression(paste(lambda))) is not the same as your sub = "lambda = 0.7" Not sure why you think it is. In any case, you need to learn about R's "plotmath" capabilities for constructing mathematical annotation in plot labelling. See ?plotmath. Better yet, as this is complex and rather difficult, do a web search for "R plotmath tutorials" (perhaps in rseek.org) to get you started.

Hi Rosa something like plot(1,1, sub=expression(lambda^"2")) So with your example, do you want something like plot(c(1:5), CRP7raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5) , xlab="Day in ICU", ylab="CRP (mg/dL)", sub = mtext(expression(lambda^2))) CRP7graph <- apply(CRP7, 1, lines, col="gray") Cheers Petr> -----Original Message----- > From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of Rosa Oliveira > Sent: Friday, July 28, 2017 5:07 PM > To: r-help mailing list <r-help at r-project.org>; R-help at r-project.org > Subject: [R] Superscript and subscrib R for legend x-axis and y-axis and colour > different subjects in longitudinal data with different colours > > I am trying to make a x-axis and y-axis titles with both a special character and a > subscript.
