Hi,
I am trying to plot multiple lines on one plot such that all lines are of
the same color (black) and continuous. I need to distinguish these multiple
plots from each other by using different symbols (I am using pch=). However,
all my lines are broken on both sides of the symbols. This unfortunate (and
unsightly) behavior seems to be the default. In my search of the help
archives for R over several days, I have not been able to solve this
problem. I would appreciate any help and suggestions. My code for the plot
is below (minus the data):
exa1.1 <- read.table("multcol.txt", header=T, sep=' ')# Total of 4
columns; first one to be on x-axis
attach(exa1.1)
names(exa1.1)
exa1.1
plot(exa1.1$Year, exa1.1$EM, ylim=range(exa1.1[,-1]), type = 'b' ,pch=16,
main = ""), las=1, cex.main=1.75,lab =c(12,8,10), ylab="", xlab="", )
lines(exa1.1$Year,exa1.1$IM,type='b', pch=1)
lines(exa1.1$Year,exa1.1$BM,type='b', pch=17)
mtext(side = 2, text = "Klett units", line = 3.5, cex=1.2)
mtext(side = 1, text = expression(Time~at~37*degree*C~(minutes)), line =
2.75,cex=1.2)
Regards,
Tariq
