R help - Jul 2017 - 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")

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

OOps!   Either  plot( ...,  sub = *)
        or	plot( ... ) ; mtext(*)

but not both!
