Dear Gregory, How can I avoid using tab character when all I want to do is to print a model summary on my pdf device using textplot()? How do I set the font size? If you mean using cex inside textplot, then it does not work. Whether cex is 1 or 0.2 I get the same result, exemplified here:
Call: lm(formula =...) Resuduals: ... Coefficients Estimate (intercept) 1.32 ... ... ... ... Std.Error t-value (Intercept) 0.2 0.1 ... ... ... ... ... ... Pr(>|t|) (intercept) 0.01 ... ... ... ... −−− Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 Residual standard error: 1.748... Is there no solution to this problem? I am using Vista, R2.6.0 patched, RWinEdt. textplot(capture.output(summary(.model)), valign="top", halign="left", cex=0.5) Thanks in advance, Jonas On 11/1/07, Gregory Warnes <[EMAIL PROTECTED]> wrote: > Hi Jonas, > > By default, textplot() attempts to automatically select a font size > that is 'just big enough, but not too big'.
