plotting multiple lines on single graph ggplot2
Hello everyone
I have some data of the following type.
100 200 300 400 500
1.1 1.2 1.3 1.4 1.5
600 700 800 900 1000
1.5 1.7 1.9 2.0 2.4
With plot() and points functions I can plot these 4 lines of data. But
I dont know how to do it with qplot or ggplot functions. The scenario
is something like this: the hundreds should appear on x-axis and the
fractional values of y axis.
Thanks alot.

Masking oceans using polypath
Hi R-help
I am trying to mask the ocean from an image plot I have made.
Here is some example code:
library(mapdata)
image(x=110:155, y =-40:-10, z = outer(1:45, 1:30, "+"),
xlab = "lon", ylab = "lat")
outline <- map("worldHires", plot=FALSE) # returns a list of x/y coords
xrange <- range(outline$x, na.rm=TRUE) # get bounding box
yrange

help to use ppp in spatial analysis
Hi,
i am using spatstat package for spatial data analysis and now i have a problem to create a point pattern. The points are in file "points.txt" (first column for Latitude and second column for Longitude ) and I imported them and separated each columns in two arrays x and y. If I plots x and y ( e.g plot(x,y) ) the result appears in square area without problems and the scale is

plot() axis problem
This posting just illustrates the problem with plot()
x<-1:20
y<-c(1:10,301:310)
plot(x,y)
xrange<-c(1,10)
plot(x,y,xlim=xrange) #uses ylim=range(y)
This is the default behaviour of plot() and I think it is not sensible.
By default the range of the y axis should span the y values corresponding
to the points plotted. In this example the yaxis should span 1-10 rather
than 1-310. This does

Beginner Q- dates in the xrange?
Hi all- terribly beginner question here, but I can't figure out how to put
dates as the values for my x range in a plot. Example:
xrange <- results$current
yrange <- results$DIFF
plot(xrange, yrange, type="n", xlab="Date", ylab="Differential")
lines(results$DIFF, type="l", lwd=1.5, col="red")
Where xrange is:

heavy graphs
Dear R community, I am creating large graphs with hundreds of
thousands of datapoints. My usual way for output was pdf, but now I am
getting file sizes of >30Mb that do not open well (or at all) in Adobe. Is
there a way to reduce the resolution or get rid of overlaying datapoints?
Any other idea is also warmly welcome!
Thank you and wishing you a good day!
Georg.

complex plots using layout()
Dear r-help,
I am trying to plot several scatter plots with marginal histograms on
one page. Ideally, a page is equally divided into 4 figure regions.
Within each figure region, a scatter plot with marginal histograms will
be plotted.
I followed Dr. Paul Murrell's code released online to successfully plot
the scatter plot with marginal histograms. The code applies "layout()"

stars graphs
Hi listers,
A few days ago I posted a question about the use of the stars function
on selected lines of a frame. Thanks to two helpers, a closer look at
the scale argument allowed to partially solve the problem. Yet I still
have a problem with stars.
Allow me to explain what I intend to do (sorry for my poor English and
the long post):

Help boxplot to add mean, standard error and/or stadard deviation
Dear researchers
I wish to plot a box plot without the mean line (the black line) and plot
only the mean (red square). Futhermore, is it possible to add standard
error and/or stadard deviation?
This is an example
mytest <- c(2.1,2.6,2.7,3.2,4.1,4.3,5.2,5.1,4.8,1.8,1.4,2.5,2.7,3.1,2.6,2.8)

Combined plot: Scatter + density plot

in order to save space for a publication, it would be nice to have a
combined scatter and density plot similar to what is shows on

I wonder if anybody perhaps has already developed code for this and is
willing to share. This is the reproducible code for the histogram

asking about contour plot with R
I'm working in Rosario, Argentina, trying to plot some contours.
I found the function "draw.contour" created by James Forester at
R-bloggers. If you take a look at that function you'll see it's very
useful!
But I have a problem with it and James is trying to help me (but also
asked me to seek for more help) I hope you can help me (don't worry if you
can't):

windows device transparency issue
I read in a thread in r-help today that the windows device in 2.6 supports
transparency, so I tried an example and had some issues. The density plots
should be filled with transparent color in the following example (similar to
the points), however the color is "fully" transparent. This works in the
Cairo device, but not in the windows device.
Thanks,

Problema con el subset

Agradeceros de antemano vuestro tiempo y paciencia ya que soy un poco

the proper way to use panel functions in lattice package?
Hi,
I was trying to stack a topographic map readed in from esri shapefile with a
contour map and a vector map. However, the plotMap(maptools) and

This I can do by the standard spatstat prodcedure via owin. I then try to

I'm just beginning with R, and i've got a little problem, I would like
to have my own xrange and yrange on the graph when I plot a matrix, and
not the one R creates automatically.
