similar to: superscripts in xyplot labels

Dear List-members, Hopefully someone will help through my confusion: In order to get the same coefficients as we get from the following ## require (MASS) summary ( lm(Gas ~ Insul/Temp - 1, data = whiteside) ) ...................... we need to do the following (if we use model.matrix to specify the model) ## summary ( lm(Gas ~ model.matrix(~ Insul/Temp - 1) - 1, data = whiteside) )

Page 140 of MASS uses the function xyplot. But I don't find it in R. Is there a package that I should load to use xyplot. Or there is a function with a different name in R that does the same thing as xyplot in S. xyplot(Gas ~ Temp | Insul, whiteside, panel = function(x, y, ...) { panel.xyplot(x, y, ...) panel.lmline(x, y, ...) }, xlab = "Average external temperature (deg. C)", ylab

Hi, How would one go about determining if the slope terms from an analysis of covariance model are different from eachother? Based on the example from MASS: library(MASS) # parallel slope model l.para <- lm(Temp ~ Gas + Insul, data=whiteside) # multiple slope model l.mult <- lm(Temp ~ Insul/Gas -1, data=whiteside) # compare nested models: anova(l.para, l.mult) Analysis of Variance

A pragmatic solution could be to create a simple linear regression example with variables in the global environment and then another example with a data.frame. The latter might be somewhat more complex, e.g., with several regressors and/or mixed categorical and numeric covariates to illustrate how regression and analysis of (co-)variance can be combined. I like to use MASS's whiteside

Hi- A journal has asked me to make all of my text annotations on a figure at 10-point size. For the most part this is easy, e.g. by creating figures with: pdf(..., family='Times', pointsize=10) But where I have superscripts (or subscripts) in axis labels, the default seems to be to shrink the superscripted text slightly. For example this code:

Although I see similar, but more complex, questions addressed in the help archive, I'm having trouble adding superscripted text to the y-axis labels of some figures, and I can't find anything in the R documentation on this. I have: ylab="BA (m2/ha)" but I want the "2" to be superscripted. Thanks in advence for the help, or for pointing out the appropriate help file.

R folks, As an R novice, I struggle with the mystery of subsetting. Textbook and online examples of this seem quite straightforward yet I cannot get my mind around it. For practice, I'm using the code in MASS Ch. 6, "whiteside data" to analyze a different data set with similar variables and structure. Here is my data frame: ###subset one of three cases for the variable

hello, i need to add legend text: "4th-root transformation", with the "th" superscripted - tried much - but nothing worked.. thanks for any hints, kay ----- ------------------------ Kay Cichini Postgraduate student Institute of Botany Univ. of Innsbruck ------------------------ -- View this message in context:

In "Modern Applied Statistics with S-Plus" 3rd ed., footnote on page 153 regarding a model lm(Gas~Insul/(Temp+I(Temp^2))-1,whiteside), I read "Notice that when the quadratic terms are present, first degree coefficients mean 'the slope of the curve at temperature zero', so a non-significant value does not mean that the linear term is not needed.

Hello All, When I use the following lines of code to create a plot and add labels with R-square values the labels have a superscripted R2. library(lattice) xyplot(PropHatchedNests$Phatched + PropHatchedNests$PropNests + PropHatchedNests$meanHSI + PropHatchedNests$RelMeanEggsNest ~ PropHatchedNests$Year, type = "b", scales=list(tick.number=length(PropHatchedNests$Year)),

so i am having this question what should i do if the give data file (.txt) has 4 columns, but different lengths? how can i read them in R? any idea for the following problem? Gas consumption (1000 cubic feet) was measured before and after insulation was put into a house. We are interested in looking at the effect of insulation on gas consumption. The average outside temperature (degrees celcius)

Hello everyone, Can anyone tell me how do I restore data in a data.frame provided by base R libraries (MASS) ? I uninstalled R then installed it again and I still see the new changes I made!!!??? (eg. whiteside$Temp=1 ==> 1 overwrote all the rows, I want the old values :( !! Please HELP! -- View this message in context:

Hi all, I have currently been using the book Modern Applied Statistics with S from Venables and Ripley. At chapter 6 on Linear Statistical models I wanted to produce the plot as shown by "Figure 6.1" using Whiteside's data. xyplot command seems not to work on my version of "R"(version 1.7.0) running on different environments (Win XP, Win 98 and Win 2000). I then used the

Dear R users, I recently developed a plotting function in R and introduced it to my coworkers. The function is designed to make plotting easier and more efficient, which will in turn be more cost-effective for the company. The reviews for the function have been positive thus far, except for one issue -- addition of superscripts to the title. We need superscipts in the titles sometimes to

I agree with Steve and Achim that we should keep some examples with no data frame. That's Objectively Simpler, whether or not it leads to clutter in the wrong hands. As Steve points out, we have attach() which is an excellent language feature - not to mention with(). I would go even further and say that the examples that are in lm() now should stay at the top. Because people may be used to

I would like to insert a superscript in a body of text (e.g., a title or axis label), where the superscript is not necessarily at the end of the text. For example, suppose a title read, "This is a Test^1 of the Emergency Broadcast System" where there is a superscript 1 after the word Test. As a starting point for what I'm trying to do, the following shows a superscript:

Hi, I have a CSV file with various biological reactions. Subscripts, superscripts, and italics are encoded in carats, and I was wondering if R can actually recognize those and print actual superscripts, etc. Here's an example: <i>S</i>-adenosyl-L-methionine + rRNA = <i>S</i>-adenosyl-L-homocysteine + rRNA containing
