how to add mean value to regression line using ggplot?
I have generated plot using ggplot, and i would like to add mean value to the
regression line as a marker. how to do it?

Change default order of colors & line types
Dear R users,
I'd like to change the default order of colors & line types.
Especially I am using ggplot2 and using color Set1.
In Set1, the default color order is red, blue, green, violet,.. ect.
However, I want to put red in fourth (not first).
Likewise, I want to change the order of default linetype. I want to
put "solid" line in fourth.
How can I do thses?

legend order in ggplot2
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_a",
"name_c". I'd like to legend to present in the order: the "name_b" at the
top, and "name_c" at the bottom.
As a consequence, the legend is indeed in the order:

Lattice plot questions
Win2k, R1.7.1:
I am currently working with some growth curve data from a

drawn at 0, 2, 4, 6, 8, and 10 weeks. For the purposes of the
project, it would be helpful if I were able to do the following:

Hi John,
You can try the following:
override.linetype=c("twodash","solid")
p <- ggplot(obs, aes(x = Timestamp))
p <- p + geom_line(aes(y = air_temp, colour = "Temperature", linetype
="Temperature"))
p <- p + geom_line(aes(y = rel_hum/5, colour = "Humidity",
linetype="Humidity"))
p <- p +

In this example, the author uses two colors for the two lines, but the
line shapes are the same -- both are solid. Could each line have its own
color as well as its own shape? For example, can I make the red line with
the linetype "twodash", while the blue line with the

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 =

mapping of colornames into hsv: half way done
Ok,
now we have the mapping of color names to color codes (see below) and
conversion to rgb (something like Ben Bolker's function), but how to convert
rgb to hsv?

legend order in ggplot2
Hi,
I ran your code, but the results were not as expected. After I ran the
code by "source", it return
No id variables; using all as measure variables
> p2
and no line or legend is on the graph (as attached)
Am I doing anything wrong?

Hi
Your approach seems to me rather complicated. I would reshape data before plotting and maybe also change order of levels in resulting variable factor
library(reshape2)
dfm<-melt(df)
dfm$variable<-factor(dfm$variable, levels=levels(dfm$variable)[c(2,1,3,4)])

Change the legend order by order function
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_c",
"name_a". I'd like to legend to present in the order: the "name_b" at the

Could it be done by order function or its inverse?

How to shade area between lines in ggplot2
Thank you, but this split the area into two and distorts the shape of
the plot. (compared to

linetype = "dashed", col = "royalblue") +
geom_abline(slope = slope_1, intercept = intercept_1 + 1/w[2],

What about something like

How to shade area between lines in ggplot2
Hi
Put fill outside aes
p+geom_ribbon(aes(ymin = slope_1*x + intercept_1 - 1/w[2],
ymax = slope_1*x + intercept_1 + 1/w[2]), fill = "blue", alpha=0.1)
The "hole" is because you have two levels of data (red and blue). To get rid
of this you should put new data in ribbon call.
Something like
newdat <- trainset
newdat$z <- factor(0)
p+geom_ribbon(data=newdat, aes(ymin =

Change the legend order by order function
There are two key concepts you seem to be unaware of regarding ggplot: 1) you really need to put your data in long format to work with multiple curves, and 2) the column containing the names of the curves should be a factor with levels in the order you wish them to be presented in the legend (bottom to top). I am not in a position at the moment to give you a full reprex, but Google can probably
