ggplot2, coord_equal and aspect ratio
Hi everyone, Hi Hadley,
I am a heavy user of coord_equal() in ggplot2 since most of my data is
spatial, on x,y coordinates. Everything works. However by enforcing an
aspect ratio of 1 for the plotting region, coord_equal() usually
wastes a lot of space if the region of interest is not a perfect square.
For example:
x=runif(10)
a=data.frame(x=x*3,y=x)
ggplot(data=a, aes(x=x,y=y)) +

ggplot and xlim/ylim
Hello everyone,
I am (happily) using ggplot2 for all my plotting now and I wondered
is there is an easy way to specify xlim and ylim somewhere when using
the ggplot syntax, as opposed to the qplot syntax. Eg.
qplot(data=mtcars,y=wt, x=qsec,xlim=c(0,30))
<->
ggplot(mtcars, aes(y=wt, x=qsec)) + geom_point() + ???
Indeed the ggplot syntax is in general more flexible and powerful and

ggplot2 qplot and add
Hi there,
I have some simple frequencies I want to plot into one graph. I had it
working, and now I can't figure out whats going wrong. All the data is
stored in a dataframe, and i finally managed to order the factor correctly!
Each column is a variable and contains integers for the same set of values
in the column that contains the headers for each row (graphLabels).
So, I get the data

ggplot inside cycle
Dear all
I want to save several ggplots in one pdf document. I tried this
for (i in names(iris)[2:4]) {
p<-ggplot(iris, aes(x=Sepal.Length, y=iris[,i], colour=Species))
p+geom_point(aes(size=3))
}
with different variations of y input but was not successful. In past I
used qplot in similar fashion which worked

ggplot2: changing axis labels in ggplot()
Hi all,
For various reasons, I need to use ggplot instead of qplot for a complex
figure. Everything is working fine, except I cannot figure out how to rename
the axis labels in ggplot. I have pasted a simple example below. Any ideas
on what I am doing wrong?
Thanks for your help.

Question about ggplot2
Hi all,
Is there any way for me to to string in the argument of qplot or ggplot? for
example
qplot(x='carat',y='price',data=diamonds,geom=c('point','smooth'))
instead of
qplot(x=carat,y=price,data=diamonds,geom=c('point','smooth'))
Thanks!!

GGPLOT/QPLOT Boxplot with summary
I'd like to generate a boxplot that has BOTH the overall distribution of a
continuous variable (say age), and then a boxplot for each level of a
stratifying variable (e.g. site). Does anyone have prototype code for this?
Thanks,

ggplot2 barplot: extra markers in graph
Dear List,
(self-contained example + version info at the bottom)
I'm having trouble producing a barplot using the functions in ggplot2. When I use the position="dodge" option, the bars are plotted but also a number of spurious markers. More specifically, a number of black dots are plotted in the graph that should not be there. This behaviour is not seen when calling the same

But if I use qplot to generate the plot (which is my aim):

and with the real data I get quite a lot of overplotting, so I would
like to add an alpha channel.
In addition, I would like to be able to control which colors are used

qplot (ggplot2) faceting histogram with missing values
Hi,
I've run into a difficulty with qplot function (in the ggplot2
package). I can facet histograms even when the faceting variable
contains missing values, but only so long as the faceting variable is
not a factor.
Example:
y1 <- rnorm(10)
x1 <- c(rep(1,5), rep(2,4), NA)
x2 <- factor(c(rep(1,5), rep(2,4), NA))
library(ggplot2)
