Hello,
I am new to R and have read the documents related to graphics but have
not come across a description of how to change the maximum scale on a
graph. Below is sample code that sets up a plot window with a 0 Minimum
to 10 Maximum, X and Y coordinate system:
x <- c(1,2,3,4,5,6,7,8,9,10)
y <- c(1,1.5,2,2.5,3,3.5,4,4.5,5,5.5)
plot(0:10, 0:10, type = "n" )# setting up coord. system
points(x, y, col = "red", cex = 1.5)
I now want to change the maximum Y axis scale to 6. I am using the
'points' function to plot 'x' and 'y' because my 'real' data is X and Y
coordinate based. When I try to change the maximum Y scale to 6 as in
the following code segment, I get the following error:
plot(0:10, 0:6, type = "n" )# setting up coord. system
Error in xy.coords(x, y, xlabel, ylabel, log) :
x and y lengths differ
How do I change the maximum Y scale to 6?
Thanks,
John Fisler
