[R] Trendline for a subset of data

[Steve Murray]

Dear all,

I am using abline(lm ...) to insert a linear trendline through a portion of my data (e.g. dataset[,36:45]). However, I am finding that whilst the trendline is correctly displayed and representative of the data portion I've chosen, the line continues to run beyond this data segment and continues until it intersects the vertical axes at each side of the plot.

How do I display the line so that it only runs between point 36 and 45 (as shown in the example above) as doesn't continue to display a line throughout the rest of the plot space?

Many thanks,

Steve
