[R] Help with scatterplots in R

[Sarah Chisholm]

Hi John,

yes, you are right. Here is what I have done:

plot(DateJonEnd1, End1Jon,
   main="Weekly Training at Endurance 1", xlim=c(13700,14750), xlab="Date",
   ylim=c(0,350), ylab="Volume at Endurance 1", type="b", las=1)

Where DateJonEnd1 is the date of weekly Training, classified as "date" and in the format 2010-07-28. I have the data from 2007-05-01 to 2010-03-31.

End1Jon is a numerical value, as an indicator of the volume of a particular type of training per week. When I plot a years worth of data, R automatically plots the months on the x-axis, however, as soon as the data spans more than a year R only gives me the years on the x-axis. However to compare the graphs, I would prefer to have the months on the x-axis, as well as the year.
I have attached one of the graphs as an example.

Hope this makes it a bit clearer.
Sarah

I think that we need an example of what you are doing before anyone can really answer that question.

At the moment we don't even know how you are plotting the scatterplot.
