...ersion of SimpleR, I wanted to to download the respective data: "The data sets for these notes are available from the CSI math department (http://www.math.csi.cuny.edu/Statistics/R/simpleR) and must be installed prior to this." There it says: "The simpleR package is now inside the UsingR package available from CRAN. In the Windows GUI, this may be installed from a menubar item. Otherwise, the following command > install.packages("UsingR") will work ..." I did, and got a package of Content type 'application/x-gzip' length 502288 bytes (490 Kb) downloaded...

I am a new R user and so I thought I could start with "Using R for Introductory statistics" by Verzani. In order to use some of the functions and datasets I have to install the simpleR package which is is now inside the UsingR package. I did so using >install.packages("UsingR"). However, the functions such as "simple.freqpoly.R" do not work. I also tried to install the Simple_0.4.zip available by the author, but I get the following message: Error in gzfile(file, "r") : unable to open c...

Hello- Since my data bank in SPSS has > 40 variables, I think that R crashes because of the memory limit. In Maindonald?s UsingR text, on pg 3, there?s a footnote that reads: "If you want larger memory space than the default you may want a target akin to <path to binary>\rw091\bin\rgui.exe --visize 30M --nsize 1000K [The default is --vsize 6M --nsize 250K (...)] I tried that, but R still crash...

I'm using Verzani's "Using R for Introductory Statistics" to teach a Research Methods in Psych course, and it recommends simple.median.test() for sign tests, which is in the Simple package--but nowhere I can find has ever heard of the Simple package! Anybody ever heard of this function or this package? cheers, Krysta ---------------------------- Krysta Chauncey, Ph.D.

Hello, I am using the function simple.violinplot from the package UsingR. I have some outliers in my dataset so that the distribution has very long tails. As a result, the y-axis of the output of simple.violinplot extends to very large values. I would like to zoom on the y-axis with a command such as ylim=c(a,b), as in boxplot(x,ylim=c(a,b)). However, doing simple.violi...

Hi all, I'm interested in doing a multiple density plot on a number of columns in a dataframe. >DF lineA.1 lineA.2 lineB.1 lineB.2 r1 5.355354 6.665575 10.288498 11.74750 r2 3.643415 5.427600 11.407112 13.97065 r3 5.813674 6.438502 9.628871 11.57456 r4 5.241340 5.125049 10.456221 12.35381 r5 4.640885 8.635518 8.344704 11.98484 r6 4.559852 6.416171 10.419599 10.89247 r7

...don't know how to use R for producing growth charts. We are collection data of Age, Weight and Length. The data are used to produce diagnosis-specific Growth charts (like the CDC Growth Charts: http://www.cdc.gov/nchs/data/nhanes/growthcharts/set1clinical/cj41l017.pdf) Data-example is in the UsingR package as data(kid.weights). In the CDC-papers a LMS approch is described. Cole has programmed the methology (I guess) in a <R 2.0.0 package called lmsqreg: """ > library(lmsqreg) Error in library(lmsqreg) : lmsqreg' is not a valid package -- installed < 2.0.0?) &quot...

Estimadas y estimados miembros de la comunidad. Junto con saludar, les escribo este mensaje porque estoy interesado en desarrollar un taller de estadística descriptiva con R para estudiantes de secundaria. El objetivo es que a través de un conjunto de datos puedan calcular medidas de tendencia central, dispersión, calcular correlaciones y hacer gráficos. Actualmente, he realizado un taller

I also tried to load the package 'UsingR' DOTplot(y0) DOTplot(y1) These two functions can plot the graphs I need but I cannot label the x-axis, choose the type of the dot, limit the x-axis, etc. these features don't work in DOTplot. Is there a way I can get a dotplot in R which is look like the plot graphed by DOTplot but has the...

Hi, I'd like to add "alpha" in latex code to my image. Any suggestions? library(UsingR) BagA = c(rep(10,6),rep(20,5), rep(30,4),rep(40,3),rep(50,2),60,70) BagA BagB = c(10, 20,rep(30,2),rep(40,3),rep(50,4),rep(60,5),rep(70,6)) BagB par(mfrow = c(2, 1)) DOTplot(BagA) abline(v=60,lwd=2,lty=2,col="red") text(65,3, "alpha-->", col=2) abline(v=50, lwd=2, lty=2, col...

Dear WizaRds, unfortunately, I have been unable to replace the '99' and '999' entries in library(UsingR) attach(babies) as definitions for missing values NA, because sometimes the 99 entry is indeed a correct value. Usually, or so I thought, NAs can easily replace a, say, 999 entry via mymat[mymat==999] <- "yodl" in a matrix or data frame. Alas, the babies' dataset also includes 9...

Hello, I would like to plot my data in a fashion similar to a boxplot, but plot the true data points without a box, just overlay lines of the summary generated by the boxplot. I have less than 10 observations within each group, so I think showing the actual data would be more effective than the box of the boxplot. I have been unable to find a way to do this. Here is example data: >

Dear All, Can R produce dot plots like the one of the following picture: http://en.wikipedia.org/wiki/Image:Dotplot_of_random_values.png ? I have tried dotchart, but no success. Thanks in advance, Paul

...nd for loops to print everything. I'd also be happy if I could pull just the Pr out, as I could interactively like so: > print(anova.ag.m2529.az$Pr) [1] 0.004392059 NA So what am I misunderstanding about how the language works? I've been all over the web and through the usingR.pdf file but can't find an example that shows something like what I'm trying to do. What exactly (data frame, table, function, character string, etc.) is stored in 'anova.ag.m2529.az' if the commands that created it were: > aov.m2529.az=aov(year~time,data=ag.m2529.az) > anov...

...ject,sd.fit=T,type="conf/pred") and calling the result a confidence/prediction band. Since there is no specific probability statement that can be attached to these connected confidence/prediction intervals, this does not seem reasonable to me. This is done, for example, in ISWR pg. 105, UsingR for Introductory Statistics pg 296, and Linear Models with R pg. 39 (Although in this instance the intervals are called 95% "pointwise" confidence bands versus simply 95% confidence bands.) To make a confidence/prediction band, one should construct simultaneous confidence/prediction int...

Hi, I need to keep a running count of events that have happened in my data.frame. I found a document called usingR that had an example of doing this for random coin flips and I tried to modify it. It seems to sort of work in the beginning, but then it stops and I don't understand why. I'm trying to duplicate essentially the Excel capability of =SUM($A$1:$A(Row number)) The example looked like this:...

Faraway's book titled "Practical Regression and Anova using R", with full text available online at: http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf refers to a data set, stat500, which compares midterm and final grades. It can be used to illustrate similar concepts. A google search for faraway.zip will locate the actual data. --- Date: Sun, 15 Feb 2004 10:37:08 -0800
