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?

color = a, shape = factor(sex),
linetype = factor(sex)))

ggplot two-factor legend
Hi
I am using ggplot to visualise y for a two-factorial group (Bio: 0 and 1) x
= 6 years. I was able to adapt the colour of the lines (green and red) and
the linetype (solid and dashed).
Challenge: my code produces now two legends. One with the colors for the
group and one with the linetype for the group. Does somebody have a hint how
to adapt the code to produce one legend? Group 0 = red and

ggplot two-factor legend
If I follow your question, you want redundant aesthetics. Ggplot normally notices correlated aesthetic mapping variables and merges the legends, so the most likely answer is that your data are not fully correlated in all rows. I have also seen this where data are drawn from different dataframes for different layers since it is hard to merge factors, but I don't see that here.

geom_smooth with sd
Dear community
Using after_stat() I was able to visualise ggplot with standard deviations
instead of a confidence interval as seen in the R help.

geom_smooth(aes(fill=Bio,
ymax=after_stat(y+se*sqrt(length(y))), ymin=after_stat(y-se*sqrt(y))) ,

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?

geom_smooth with sd
Hi!
This is probably completely off base, but your ymin and y max setup lines
are different. One uses sqrt(y), while the second uses sqrt(length(y)).
Could that play a part, please?
Thank you

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:

Hi John,
You can try the following:

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 +

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?
Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker
Details below

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 =

https://rpubs.com/MarkusLoew/226759
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

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
