Correlograms: using boxes and different variables on rows and columns
I'm trying to make correlograms using corrgram. See below for a simple
example.
####
library(corrgram)
data(baseball)
vars1 <- c("Assists","Atbat","Errors","Hits","Homer","logSal")
vars2 <- c("Putouts","RBI","Runs","Walks","Years")

corrgram (package corrgram): how to plot multiple correlograms in the same page?
Hello,
I am trying to plot a few correlograms on the same figure, with the function corrgram() from the package corrgram. However, the function does not seem to use the base graphic system, as setting out the multiple figure layout with, e.g., par(mfrow=c(2, 2,)) does not work.
Does anybody know a workaround for this?
Many thanks in advance for any advice
best

Correlograms
I would like to make a correlogram in which I also have a correlation matrix
instead of one of the panels.
Is that possible?

Cross-correlograms or cross-variograms in R?
Hello group,
For my PhD I'm working on a spatial sampling grid. I do have two data sets
which I'd like to compare using cross-correlograms or cross-variograms.
Is this an option in one of the R-packages? I've been searching the R-help
archive and the available package-documentations, but I can't find how to do
this.
Thanks in advance,
Ren?.

R help: Correlograms
Hello,
I have time series and need to draw simple and partial correlograms with associated Q-statistics (the same as in EViews). Can I do it in R? Thanks

R help: correlograms
Dear colleagues,
Where I can find tools for drawing correlograms (graphical representations of
autocorrelation and partial autocorrelation functions)?
Thank you,

corrgram
Hello,
are there fixed threshold values for the changes between different
shades of blue in the corrgram?
Or is a chang relative depending on the data?
I didnt get it in manual.
Thank you very much, best regards

[PATCH 1/3] nv50: rework primid logic
Functionally identical but much simpler. Should also better integrate
with future layer/viewport changes/fixes.
Cc: 10.1 <mesa-stable at lists.freedesktop.org>
Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu>

Not *strictly* necessary in stable, but it will make backporting later fixes
easier. No regressions in piglit.

problem with corrgram function
Dear list,
I have a problem with the "corrgram" function. It does not seem to
"color" large negative correlations, while the same correlation, if
positive, provides no problems. Is this a bug?
require(corrgram)
a = seq(1,100)
b = -jitter(seq(1,100), 80)
cor(a,b) # r about -.96
c=as.data.frame(cbind(a,b))

How to improve the robustness of "loess"? - example included.
Hi,
I posted a message earlier entitled "How to fit a line through the
"Mountain crest" ..."
I figured loess is probably the best way, but it seems that the
problem is the robustness of the fit. Below I paste an example to
illustrate the problem:
tmp=rnorm(2000)
X.background = 5+tmp; Y.background = 5+ (10*tmp+rnorm(2000))
X.specific = 3.5+3*runif(1000);

Analyzing large transition matrix
Let's say you have a dataframe of car trade-ins. For example, each row
contains
oldcar newcar qty
and a typical entry could be
lexus bmw 1
I put the qty column to allow for fleet purchases, where one purchase
may convert multiple cars at once.
I'd like to show what's going on. I could do a histogram of newcar to
show the frequency each type of car is bought. If there

correlogram in spatial producing values outside [-1,1]
Dear all,
I'm using the correlogram function in the spatial library to calculate
spatial correlograms of radar data. However, I'm finding that the
resulting values are often outside the range [-1,1], usually only at
larger distances of separation.
I'm not sure whether to be overly concerned about this, or dismiss it as
some artefact of the data. Has anyone had similar experiences?

merge some columns
Dear all,
I would like to know how to merge columns like:
Input file:
V1 V2 V3 V4 V5 V6
1 G A G G G G
2 A A G A A G
Desired output file:
V1 V2 V3
1 G/A G/G G/G
2 A/A G/A A/G
So for every 2 consecutive columns merge their content into one.
Thanks in advance.

how to change variable names in corrgram diagonal
given this example
library(corrgram)
corrgram(mtcars[2:6], order=TRUE, upper.panel=panel.conf,
lower.panel=panel.pie,
diag.panel=panel.minmax,
text.panel=panel.txt)
how can I change the variable names in main diagonal?
(so that I can put more informative names of variables)
I think to understand that this should be done by modifing the panel.txt
function but

Resampling Help Needed
I am using package ks() to build 3D representations of bird territories and
calculate territory volume from spatial data (simply x, y, and z
coordinates). What I want to do is determine at what sample size (#
locations collected) does the territory volume stop increasing. This should
give me an idea of the number of points needed for future seasons.
So I have a couple of birds each with 200

How to alter circle size
Hello all,
I'm trying to create a heatmap using 2 matrices I have: z and v. Both
matrices represent different correlations for the same independent
variables. The problem I have is that I wish to have the values from matrix
z to be represented by color intensity while having the values from matrix v
to be represented by circle size. I currently have the following in front of
me and an unsure

A plotting question - how to get error bars?
Dear R list,
Can anyone help with a plotting question? I'm trying to display some data
on a plot and I've almost got the format I need (see code below), but 2
things I can't get:
1. How to get "Jan","Feb","Mar" on the x=axis instead of 1:3?
2. How to get "T"s on the end of my error bars like you have in standard
scientific plots?
Any comments

Add line to plot. The line falls outside the current plot.
Hi,
I have plotted the graph of x^2 and I would like to add to
it a line that is currently outside of the plot ( the points of the line
fall outside of the plot ). When I use the function 'lines' the graphics
window does not became larger to show this line.
Is there any way I can fix this?
Also, how can I eliminate the axis from the plot?
Thank you.
