Dear helpers Is it possible to plot with a desired character? For example "tr" for training error and "te" for test error. I tried plot(x,y,pch="tr") but only appears "t" in the plot

EG: plot(c(0,1),c(0,1),type='n') text(runif(10),runif(10),'Random') The text is by default centered on the x,y location, but you can change this with the adj parameter. The text can be a vector, and it is recycled to the length of x,y: text(runif(10),runif(10),c('Foo','Bar')) see help(text) for more. Baz
Use text().
x <- rnorm(10); y <- rnorm(10)
plot(x,y,type="n")
text(x,y,rep(c("te","tr"),each=5))

This will by default place the "TextSymbol" in the plot region centered on x,y. You would first call: plot(x, y, type = "n") so that no points are plotted. Then use: text(x, y, "tr") and text(x, y, "te") for each set of x,y coordinates as appropriate. You can use the 'cex' argument to text() to adjust text size and of course others for color, etc. HTH, Marc Schwartz
Have you considered "?text"? hope this helps. spencer graves Luis Miguel Almeida da Silva wrote:> Dear helpers > > Is it possible to plot with a desired character?

You can plot a whole character vector of different values if you like. Duncan Murdoch
