smoothScatter
Hi, I have been trying to plot density plots using the example on:
http://addictedtor.free.fr/graphiques/graphcode.php?graph=139
I used to use this function, but I cannot get any old code or even the example to work.
library("geneplotter")
require("RColorBrewer")
x1 <- matrix(rnorm(1e4), ncol=2)
x2 <- matrix(rnorm(1e4, mean=3, sd=1.5), ncol=2)

Is there a way to avoid loading dependendent packages?
Hello R help list
I have been using the smoothScatter function within the "geneplotter"
package to make some graphs using a Sweave Rnw script called via Rscript
in a DOS/Windows batch file. The Rscript will ultimately be called by a
web service with time-out constraints, hence things need to run as
swiftly as possible.
The geneplotter package is currently loaded each time R is invoked

SmoothScatter plot range issue
Hello,
I am attempting to use smoothScatter to plot a heatmap of locations of
events in an x-y axis. When I plot the heatmap without passing xlim and ylim
parameters, it fills the plot area but the perspective is a bit skewed. I
would like to standardize these plots to a uniform window size that does not
depend on the range of values in the dataframe. However, when I resize the
plot using xlim or

smoothScatter problems
Hello,
I'm having some trouble getting a good result for a smoothScatter plot.
I have some data that I want to log-plot, but when I use smoothScatter
the result is not correct.
The problem seems to be that with the log="x" argument smoothScatter
calculates the bins linearly, so the plot will be skewed towards the right.
See for example:

Patch for legend.position={left,top,bottom} in ggplot2
Hi Hadley and everyone,
here's a patch for ggplot2 that fixes the behavior of
opts(legend.position={left,top,bottom}). If you try the following code
in an unmodified ggplot2
options(warn = -1)
suppressPackageStartupMessages(library("ggplot2"))
data <- data.frame(
x = c(1, 2, 3, 4, 5, 6),
y = c(2, 3, 4, 3, 4, 5),
colour = c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE))

Why does smoothScatter clip when xlim and ylim increased?
Hi:
Is there a way to get smoothScatter to not clip when I increase the xlim and
ylim parameters?
Consider the following example:
set.seed(17)
x1<-rnorm(100)
x2<-rnorm(100)
smoothScatter(x1,x2)
#Now if I increase xlim and ylim notice that the plot seems to be clipped at
the former xlim, and ylim boundaries:
smoothScatter(x1,x2, xlim=c(-5,5), ylim=c(-5,5))
Thanks.

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

smoothScatter function question and adding a legend
Hello,
I have a few questions, regarding the smoothScatter function.
I have a scatter plot with more than 500,000 data points for
two samples. So, I am wanting to display the density in colors
to convince people that my good correlation coefficient is not
due to an "influential point effect" and plus, I also want to make
my scatter plot look pretty. Anyway ...

reversing xlim, ylim in smoothScatter
Hello,
I have found that in smoothScatter it is not possible to reverse the axes plotted (R version 2.9.0) . It appears that this arises from the hard coding of xlim and ylim in smoothscatter.R in the lines :
x <- x[ xlim[1] <= x[,1] & x[,1] <=xlim[2], ] (line number 25)
and
x <- x[ ylim[1] <= x[,2] & x[,2] <= ylim[2], ] (line number 31)
This results in a x

density plot on a log scale
I'm working with a large dataset - large enough that when I do a scatter plot
the points all blur together, so I want to plot their density by color - a
heat map or something like that. I've used smoothScatter for tasks like
this, but the problem is that my current dataset really only looks good on a
log-log scale. When I do the following command

Hi!
How to find out which plot function is used when i call

The reason why I would like to know it is that after loading some self written R functions

Trouble with line of best fit
I don't usually do much with graphs in R, and this is my first time adding a
line of best fit. Hopefully this is an easy problem to solve.
I'm looking at a variable called soloKills along the range 5:28. Here are
all my commands, in script form:
range=5:28
graph=soloKills
title="Solo kill/death data"

How do I plot a line followed by two forecast points?
Good day all,
I'm trying to plot a continuous line plot, which is followed by two
forecast points eg. one forecast point is 12 months out, and another
24 months out from the last date of the line plot.
In my attempts so far, the second plot (the forecast points) is scaled
against a new axis scale, thus the two plots are not directly
comparable (I need the forecast points to be scaled

image quality
dear all,
I am writing a sweave documentation for my analysis, and I am plotting huge
scatter plot data for microarray.
unlucly this take a lot of resource to my pc because of the quality of the
image which is to high (I see the PC get stuck for each single spot).
how can I overcome this problem? is there a way to make lighter image?

Building a time series.
I have a need to build a time series and there are a couple of aspects about the time series object that are confusing me. First it seems that ts.union is not doing what I would expect. For example:
x0 <- rep(0,10)
x1 <- rep(1,10)
xt0 <- ts(x0, frequency=10)
xt1 <- ts(x1, frequency=10)
st2 <- ts.union(xt0, xt1)
> xt2
Time Series:
Start = c(1, 1)
End = c(1, 10)

scatterplot3d with categorical data

I'm trying to produce a 3d bar plot but the x and y dimensions have categorical
data -- so I only want 3 points on each axis. So I try:
