ggplot, ribbon not showing up properly
Hi,
I'm trying to plot a longitudinal data set, using ggplot and adding some
summary info (eg. mean, 1 sd bounds) using geom=ribbon. The summary
info is based on a subset of the original data (eg. less an outlier).
But I'm having trouble getting the ribbons to show up correctly. It's
probably something obvious that I'm missing as a novice at ggplot2, and
any help is much

plotting time series using ggplots
Hi,
I would like to plot a bunch of tree ring width data (time series)
using ggplots, but I'm having trouble figuring out how to do it.
My data is in a data.frame, with years as rownames and a distinct tree
ring series in each column. So, something like this:
rwl<-matrix(rnorm(800), nrow = 100)
colnames(rwl) <- paste('V', 1:8, sep = '')

ggplot2: legend
Dear all,
I produced the following graph with ggplot which is almost fine, yet I don't like that the legend for "Means" and "Observations" includes a line, though no line is used in the plot for those two (the line for "Overall Mean" on the other hand is wanted):
library(ggplot2)
ddf <- data.frame(x = factor(rep(LETTERS[1:2], 5)), y = rnorm(10))

ggplot2 geom_rect(): What am I missing here
Hi R fans,
As a newbie following the five-hour rule (after hitting my head against
the wall for five hours, post to this list), I am appealing for some
help understanding geom_rect() in ggplot2.
What I want to do is very simple. I want to generate a plot of
rectangles. Each one represents a business cycle. The x-values will be
pairs representing the start and end of each cycle. The y-values

plot.hclust: dendrogram too large for window (PR#4197)
plot.hclust:
Setting up a window for a dendrogram assumes the first link is
the shortest and the last is the longest. This is not always the
case when the clustering was done with hclust, method="median"
or method="centroid", and the dendrogram sometimes doesn't fit
within the window.
I propose the fix listed below.

incomplete final line found on <name of my sourced function file>
Dear R-ers,
I hope there is a really simple solution to my problem.
I've written a function that I saved in an .r file. I source this file
in my code. For a while it worked fine. But then when I run the line:
source("F mylineplot.r")
I started getting a warning:
In readLines(file) : incomplete final line found on 'F mylineplot.r'
I have no idea why - I tried to check and

highlighting clusters in a heatmap
I would like to draw horizontal or vertical lines on a heatmap to
highlight the clusters at some specified cut depth of the dendrogram.
As a hacked example, the following code would work if I could set the
coordinates of the top and bottom of the false color image correctly
(ymin and ymax), but the correct values seem to depend on the output
device and its size. I realize that heatmaps use a 2x2

How to shade area between lines in ggplot2
Hi
Put fill outside aes
p+geom_ribbon(aes(ymin = slope_1*x + intercept_1 - 1/w[2],
ymax = slope_1*x + intercept_1 + 1/w[2]), fill = "blue", alpha=0.1)
The "hole" is because you have two levels of data (red and blue). To get rid
of this you should put new data in ribbon call.
Something like
newdat <- trainset
newdat$z <- factor(0)
p+geom_ribbon(data=newdat, aes(ymin =

Error Bars ggplot2
Hello,
I'm attempting to plot error bars side by side rather than stacked on top
of each other with ggplot2. Here is the sample code I am using:

Tamaño plots y calidad en grafico ggplot
Hola a tod en s,
bueno, un poco al hilo de un mensaje anterior, reformulo la pregunta y
pongo código completamente reproducible, a ver si hay más suerte.
Estoy con un informe y hay que hacer algunos gráficos con datos
diferentes con ggplot2, y hay que poner el mismo tamaño para todos
ellos.
El problema es que R cambia automáticamente el tamaño del área de

geom_ribbon removes missing values
Hi everyone,
it looks like geom_ribbon removes missing values and plots a single
ribbon over the whole interval of x values. However, I'd rather want it
to act like geom_line, that is, interrupt the ribbon for the interval of
missing values and continue once there are new values. Here's an example:
library(ggplot2)
df <- data.frame(
date = seq(from = as.Date("2010-05-15"),

Unspecified [upper] xlim/ylim?
Greetings!
I would like to be able to specify a fixed (say) lower limit
for plotting, while leaving the upper limit "floating, when
plotting. The context is that the maximum in the data to be
plotted is unpredictable, being the consequence of a simulation,
whereas I know that it cannot be less than (say) 0; and I want
to fix the lower limit at 0 in any plot, leaving the upper limit
to be

ggplot2/aesthetic plotting advice
Consider the following situation:
we have quantified algal concentrations for
a variety of species using many samples at each
of three years. It seems to make sense to generate
a line plot (matplot-like), with each species plotted
as a separate line, with the points connected to emphasize
the temporal pattern.
The problem: lots of overlapping error bars.
The question: from both a

2D Random walk
I've wrote some code to simulate a random walk in 2 dimensions on a lattice.
Basically I want to add something in to make it plot it point by point so
you can see what is going on.
Heres my code for the random walk in 2d

ydir<-0

Calcular Error en modelo lineal
Buenas, una pregunta.
Si yo estoy calculando un modelo lineal, el caso más simple, 1 variable respuesta y una variable explicativa y creo un modelo, me da un R2 del 80% y quiero ver como es esa relacion entre las variables, para calcular el error de predicción del modelo, basta con ver el intervalo de confianza del modelo e irme a los extremos?
Por si no me he expresado bien, un ejemplo tonto:
