- 3. dataCrunchFont Slide 3 The font argument can be used along with main, sub, axis and lab arguments to specify the font of the title, subtitle, axes and the labels. Feature Argument Title font.main Subtitle font.sub Axis font.axis Labels font.lab The font argument takes values from 1 - 5. The font type represented by each value is shown in the above table. Value Font Type 1 Plain 2 Bold 3 Italic 4 Bold Italic 5 Symbol

- 13. dataCrunchFont Size Slide 13 The cex argument can be used along with main, sub, axis and lab arguments to specify the font size of the title, subtitle, axes and the labels. Feature Argument Title cex.main Subtitle cex.sub Axis cex.axis Labels cex.lab The values taken by the cex argument are relative to 1 i.e the default size is represented by 1 and if the supplied value is less than 1, the size of the font will be relatively smaller, and if the supplied value is greater than 1, the size of the font will be relatively bigger.
