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!!

multiple pages with ggplot2 facet_wrap?
I currently use lattice functions to produce multiple pages of plots
using the "layout" argument to specify the number of rows and columns
of panels, e.g.,
xyplot(price ~ carat | clarity, diamonds, layout = c(2, 2))
This results in 2 pages of 4 panels each. "diamonds" is a data.frame
distributed with ggplot2.
I would like to do the same with ggplot2 but have been

back-transform predictors for x-axis in plot -- mgcv package
My question is related to plot( ) in the mgcv package. Before modelling
the data, a few predictors were transformed to normalize them.
Therefore, the x-axes in the plots show transformed predictor values.
How do I back-transform the predictors so that the plots are easier to
interpret?
Thanks in advance,
Suzan

I updated/reinstalled ggplot2 and the trouble started...
Hi Ian,
Per your suggestion, I reinstalled R 2.9.0, then
I reinstalled ggplot2 on top. The problem persists.
Here's the what happens after the installation:
> qplot (carat, price, data = diamonds, alpha = I(1/10))

ways to put multiple graphs on single page (using ggplot2)

Plotting from functions
I can plot to png's fine when i run this directly from the top-level
script/console:
png('diamonds.png');qplot(carat,price,data=diamonds);dev.off()
But for some reason it's not working when that's in a function:
(function(){png('diamonds.png');qplot(carat,price,data=diamonds);dev.off()})()
I suspect this is because the qplot's return value must be

Plots don't update with xlab, etc. What am I doing wrong.
Hi,
I've been struggling with this problem the last few days and finally
discovered it's happening at a very fundamental level. Going through
Stephen Turner's tutorial on ggplot2, I entered these base graphics
commands:

ggplot boxplot - how to order categories
I am interested in creating a boxplot using ggplot or qplot where I can
specify the order of the categories being plotted on the x-axis. For
example, the following command plots the categories (diamond color) in
alphabetic order (D, E, ..., J):
qplot(color, price/carat, data=diamonds, geom="boxplot")
I want to know how I can modify this command so that the categories are

Question about ggplot2 and stat_smooth
I'm interested in creating a graphic -like- this:
c <- ggplot(mtcars, aes(qsec, wt))
c + geom_point() + stat_smooth(fill="blue", colour="darkblue", size=2,
alpha = 0.2)
but I need to show 2 sets of bands (with different shading) using 5%,
25%, 75%, 95% limits that I specify and where the heavy blue line is the
median. I don't understand how to do this with

sparse.model.matrix Generates Non-Existent Factor Levels if Ord.factor Columns Present
Good day,
Sometimes, sparse.model.matrix outputs a dgCMatrix which has column names consisting of factor levels that were not in the original dataset. The first factor appears to be correctly transformed, but the following factors don't. For example:
diamonds <- as.data.frame(ggplot2::diamonds)
> colnames(sparse.model.matrix(~ . -1, diamonds))

Styling gridExtra's title and left labels
Hi,
I'm using the gridExtra package to combine some graphs like in the
arrangeGrob example. Each of the graphs has a title but they appear much
larger than the overall combined plot title and left axis label. Does anyone
know how I can control the style / size of the gridExtra labels?

Unicode whitespace
It would be nice if R ignored more unicode white space characters.
For example, if I have "\u2028" in a command (which I get from a

smoothScatter plot
Hi, I want to make a plot similar to sm1 (attached). The code I tried is: dcols <- densCols(x,y)
smoothScatter(x,y, col = dcols, pch=20,xlab="A",ylab="B")
abline(h=0, col="red")
But it turned out to be s1 (attached) with big dots. I was wondering if anything wrong with my code. Thanks,Zhengyu
