function curve() swap axes
...Minimal working example:
S0 = 0.004
n = 0.04
tanalpha = 1.4/1.5
par(mar = c(5,5,1,1)) # b, l, t, r
curve((sqrt(S0)/n)*(0.035+(0.7+(x-0.1)/tanalpha)*(x-0.1))*((0.035+(0.7+(x-0.1)/tanalpha)*(x-0.1))/(2*sqrt((0.7/2)^2+0.1^2)+2*sqrt((x-0.1)^2+((x-0.1)/tanalpha)^2)))^(2/3),0.1,1.55,
lwd = 3, col = "royalblue4", ann = F, axes = T)
title(xlab = parse(text='a~bgroup("[", m, "]")'))
title(ylab = parse(text='Q~bgroup("[", m^3/s, "]")'))
box()
I tried to find the inverse function, but that doesn't seem to exist.
Thank you for support,

How to shade area between lines in ggplot2
Hello,
I am running SVM and showing the results with ggplot2. The results
include the decision boundaries, which are two dashed lines parallel
to a solid line. I would like to remove the dashed lines and use a
shaded area instead. How can I do that?
Here is the code I wrote..
```
library(e1071)
library(ggplot2)
set.seed(100)
x1 = rnorm(100, mean = 0.2, sd = 0.1)
y1 = rnorm(100, mean = 0.7, sd =

Ggplot: free x-scales in a facet-grid
Hello,
I have a ggplot that has the looks of the plot that I want, but it doesn't
have the right layout.
The data is an ordered melted dataframe:
- ID
- type (to use for a faced grid)
- time - type
- time - value (POSIXct)
- pos (to use for a faced grid, this is an index to split the plot)
The goal of the plot is to create a time line for each ID (different points
of time). The ID's

Font size in geom_dl (using ggplot2)
Hey everyone,
I am an R-newby... so sorry for bothering you with simple-to-solve
questions;) I have the following issue: trying to add labels to my
scatterplots (with geom_dl in ggplot2). Everything works fine, but after
checking every resource I do not find a way to change the font size of my
labels. I tried size, cex, fontsize at every position... but it always stays
the same.
