1) I need to plot a legend containing the mathematical symbol
greater-than-or-equal sign.
And I want the text to start with that symbol.
plot(110, 0.8)
categories <- expression(blank >= 85, 84.9 - 80, 79.9 - 75, 74.9 -
70, 69.9 - 65, 64.9 - 60, blank< 60)
legend(110, 0.8, categories, lty=1:7, lwd=3, col=1, merge=TRUE)
What I want is just ">=85" to be printed, but without something
(here "blank") in front it is no correct expression.
2) Also I want German type decimals, that is a comma instead of a
point.
But the problem is, that the comma is used as argument separator in
expression.
plot(110, 0.8)
categories <- expression(blank >= 85, 84,9 - 80, 79,9 - 75, 74,9 -
70, 69,9 - 65, 64,9 - 60, blank< 60)
legend(110, 0.8, categories, lty=1:7, lwd=3, col=1, merge=TRUE)
Try:
> plot(110, 0.8)
> categories <-legend(110, 0.8, c( expression(" ">= " 85"), "84,9
- 80", "79,9 - 75", "74,9 - 70", "69,9 - 65", "64,9 - 60",
expression(" "<" 60"))
+ , lty=1:7, lwd=3, col=1, merge=TRUE)
The commas inside quotes do not cause problems.
This does obviously not work. Any ideas?
Thanks,
Mark
