I would like the text plotted with 'mtext' to be alighned like it is for printing on the console. Here is what I have:
You don't provide any of the info in the posting guide (OS may be important here), or a reproducible example, which would also be helpful. But see below anyway.

I have looked at the strings and they all have the same length so it seems that mtext is doing something with the spaces so that the output is not aligned. Any ideas on how I can get it aligned (by column)?
The default font used for titles is not proportionally spaced, at
least on my linux
system, so of course they won't line up.
Try:
a <- c(" ME RMSE MAE MPE
MAPE MASE",
"original -1.034568e+07 1.097695e+08 2.433160e+07 -31.30554 37.47713
1.5100050",
"xreg 1.561235e+01 2.008599e+03 9.089473e+02 267.05490 280.66734
0.9893643")
par(mfcol=c(2,1), oma=c(0,0,4,0))
plot(1:10, 1:10)
plot(1:10, 1:10)
par(family="mono")
mtext(a[1], line= 1, side=3, outer=TRUE)
mtext(a[2], line= 0, side=3, outer=TRUE)
mtext(a[3], line=-1, side=3, outer=TRUE)
Or whatever the appropriate font family specification for your OS is.
