Dear R-users,
I'm tackling with a problem which causing me a head-ache for a long time. I
would like to create a nice x-axis to my plots, but I do not know how to
implement the method.
Imagine a matrix where you have rownames real numbers -- these rownames
should be written in the x-axis nicely. I could not find any way how.
I'll describe what I'm doing now:
I have a matrix where each column is an independent curve (number of the
columns 3-4). The rownames are the x-axis, and the names are real numbers
(converted to chars, of course). I find the max and the min among the values
in the matrix (for the y-axis) and I'm creating an empty plot. x-axis is
c(0, nrow(matrix)). Now, I'm creating the x-axis labels
Labels <- seq(1, nrow(matrix), by = 100)
axis(1, at = NULL, labels = rownames(matrix)[Labels])
At this point I'd like to have instead of "24.12333 26.45667 28.79
31.12333 33.45667" at the x-axis, an optimally placed ticks at let's say
"26 28 30 32" -- this is what I cannot achieve.
Afterwards I'm plotting the curves in different colours. I know that the
x-values are accessed by the number of their row and not rowname.
Anybody could point me into some direction, please? Thank you upfront!
