R Documentation

progression by linear ordinary least squares

makes a linear regression with projection in the future by projyears years

progols( tdate, index, projyears = 5,
         xlab = "years from first visit", ylab = "md",
         txtfont = "mono", pointsize = 12, cex = 1 )

`tdate`	visit date
`index`	index measured at the corresponding age
`xlab`	label for x-axis. Default is `age`
`ylab`	label for y-axis. Default is `md`
`projyears`	Years for projection. Default is `5`
`txtfont`	font of the text with visual-sensitivity values. Default is `mono`
`pointsize`	size of the text with visual-sensitivity values. Default is `12`
`cex`	a numerical value giving the amount by which plotting text and symbols should be magnified relative to the default. Default is `1`
