Well, as a line in the plane is determined by 2 coefficients only, I'd
guess that trying to find an R function that plots a line defined by 4
coefficients has about the same chance of success as finding a unicorn
with 3 horns.
You do understand that your linear model defines a hyperplane in your
three covariates, do you not? Or do I misunderstand what you have
requested?

It looks like qplot uses
colour=colors
to pickup colors.
At the R console type
colors()
For a list of color names and numbers.
Hope this helps.

Subject: [R] qplot and colors (Please Help)
Please help:
I am using qplot as below and want to specify a different color scheme for
race but dont know how, can someone show me.
Thanks in advance
Code and input file below:
library(ggplot2)
library(gridExtra)
d-read.table(results, header=TRUE, fill=TRUE)
plot2-qplot(X,Y,data=d,color=race,facets=TYPE~., xlab=X, ylab=Y) +
theme_bw()
grid.arrange(plot2,ncol=1)
dev.off()
cat results

[R] Accessing more than two coefficients in a plot
I've successfully plotted (in the plot and abline code below) a simple
regression of Lambda1_2 on VV1_2. I then successfully regressed Lambda1_2 on
VV1_2, VV1_22 and VV1_212 producing lm2.l. When I go to plot lm2.l using abline
I get the warning:
1: In abline(lm2.l, col = brown, lty = dotted, lwd = 2) : only using the
first two of 4 regression coefficients
Is there another function like abline that will produce a line using the
constant and three coefficients from the lm2.l regression?
lm.l - lm(Lambda1_2 ~ VV1_2, method = qr, model = TRUE, x = FALSE, y =
FALSE, qr = TRUE) # unweighted regression
lm2.l - lm(Lambda1_2 ~ VV1_2 + VV1_22 + VV1_212, method = qr, model = TRUE,
x = FALSE, y = FALSE, qr = TRUE) # unweighted regression
plot(VV1_2, Lambda1_2, ylim=yrange, tck=1, main=V(1) Parameters (V, V^2
V^0.5), xlab=VV1_2, ylab=Lambda Beta1_2,pch=19,col=red)
{abline(lm2.l, col=brown, lty=dotted, lwd=2)
abline(wlm2.l, col=gold,lty=longdash, lwd=2)
points(VV1_2, Beta1_2, pch=19, col=blue)
abline(lm2.b, col=black,lty=dotted, lwd=2)

Re: [R] where I can find more color names or color definition?
Load package fBasics library(fBasics) colors() should give you what you want. Also helpful are colorTable() colorLocator() Which I found by searching for colors from the R console help menu.

Re: [R] Automating R script with Windows 7
I created a txt file with R commands in it and then a batch file to process the
txt file. The batch file could be scheduled. The batch file is:
REM on Microsoft Windows (adjust the path to R.exe as needed)
C:\Program Files\R\R-2.13.2\bin\x64\R.exe CMD BATCH
C:\Users\Frank\Documents\R\Scripts\Multi_Graph.txt
C:\Users\Frank\Documents\R\Scripts\Multi_Graph.out
PAUSE
The text file is:
x - seq(-4, 4, length=100)
hx - dnorm(x)
degf - c(1, 3, 8, 30)
colors - c(red, blue, darkgreen, gold, black)
labels - c(df=1, df=3, df=8, df=30, normal)
pdf(C:\\Users\\Frank\\Documents\\R\\Scripts\\Norm_Graph.pdf)
plot(x, hx, type=l, lty=2, xlab=x value,
ylab=Density, main=Comparison of t Distributions)
for (i in 1:4){
lines(x, dt(x,degf[i]), lwd=2, col=colors[i])
}
legend(topright, inset=.05, title=Distributions,
labels, lwd=2, lty=c(1, 1, 1, 1, 2), col=colors)
This produces a nice plot.

Automating R script with Windows 7Hi R-users, I am trying to
automate the daily running of a simple R script from Windows 7. From
previous posts, I understand that this needs to be done with the task
scheduler. I can schedule my laptop to automatically open R at a certain
time, but not to execute a script. Secondary question: how do I save a
list of R commands so that they get executed once the file is open? Right
now, I save my code in a notepad doc and paste over in R, but there has to be
another way. I have tried saving my code as .r file using the editor and open
the file with R later but this does not seem to execute the code. I very
much appreciate the help. Vincent Deluard, CFA-- View this message

[R] Telling plot() the max y value to expect when plotting one distribution and then using lines() to add more distributions
I am plotting three Pearson Type IV distributions. It looks like I have to plot
the distribution with the highest value of y and then use lines() to add the
two distributions that are shorter / have lower max values of y. The following
code figures out which distribution has the max y value, plots it first and
then uses lines for the other two distributions with a series of three if
statements. This works. I run R from a batch file that reads the following in a
text file.
I want to graph dozens of distributions and I am looking for a more elegant way
to do this.
New to R, experienced C programmer, thanks in advance. Frank
