I am trying to generate the heat map plots from the cummeRbund package (see p22). It generates the plot. However initially, the values in h$data$variable were [q1,q2,q3,q4,...,q18] (which were set by a previous program in a particular data file located in ../cuffdiff). Below, I changed the values of h$data$variable to something more meaningful to me, however when I plot, the x-axis still has q1,q2,etc for the x-axis labels.

cuffset<-readCufflinks(dir = "../cuffdiff", gtfFile="../cuffmerge/merged.gtf", genome="GRCh38")
h$data$variable[h$data$variable == "q1"]<-"tissue-1"
h$data$variable[h$data$variable == "q2"]<-"tissue-2"
h$data$variable[h$data$variable == "q3"]<-"tissue-3"
h$data$variable[h$data$variable == "q4"]<-"tissue-4"
> class(h)
[1] "gg"     "ggplot"

How do I change the labels to something more meaningful (e.g. tissue-1, tissue-2, etc.)?
