Hello,
Recently, I have asked for a help with building graphs, and I got few
great advices. Now, my appetite is growing :) and I wander how to add
legend for two (or more) lines in following example:
matplot(DAT[, c(3,4)], type="b", ylim=c(0,8), xaxt="n", yaxt="n",
+ pch=c(21,22), col="black", lty=c("dashed","solid"), xlab="", ylab="")
title(ylab="% correct", xlab="Trial", cex.lab=1.5)
axis(1, at=1:4, labels=as.character(DAT$Trial), cex.axis=1.5)
axis(2, cex.axis=1.5)
Sincerely,
Petar
