The curves you are asked to draw here have the same basic shape but differ in their details (specifically, the means and standard deviations of these Gaussian distributions are different). Simple format of R lines functions: plot (x, y, type = "l", lty = 1). The idea is to give reasonable output for any R object. See ‘Details’. col is used to give colors to both the points and lines. Rebooted R, sourced from the command line and from the menu... None of the functions I am using are exclusive to x64 or a package (that I know of). How to Create a Data Frame from Scratch in R, How to Add Titles and Axis Labels to a Plot…. In other words, if you specify the coefficients of your regression model as the arguments a and b, you get a line through the data that is identical to your prediction line: Even better, you can simply pass the lm object to abline() to draw the line directly. David Winsemius, MD Heritage Laboratories West Hartford, CT v is a vector containing the numeric values. the y-value(s) for horizontal line(s). But first, use a bit of R magic to create a trend line through the data, called a regression model. Note that create = TRUE has no effect if the specified file exists, i.e. One point of this exercise is to show what this bell curve looks like for exactly Gaussian data and the other is to show how the lines() function can be used to add lines to an existing plot. v. the x-value(s) for vertical line(s).
