I am trying to plot data with maximum 9.70 and minimum -58.9.
I coded:
plot(BriannaJan[,3,i], type = \"line\", col=\"black\", main = \"Brianna
-60:10 generates a sequence from -60 to 10, what you need as the ylim is a min and max value (with syntax c(min, max)) instead of a sequence, try this:
-60:10
-60
10
c(min, max)
ylim=c(-60,10)
