Is there a place that shows how to create two plots that are stacked on top of each other where they share a common x-axis scale, but have differnt y-axis scale? Say have the following data: airquality Stack plot(airquality$Day, airquality$Wind) on top of plot(airquality$Day, airquality$Temp). I am interested in stacking the two on top of each other with no seam, or plotting the two lines with

Hello: I am a bit confused by this problem. Can anyone give me some advice on this I would greatly appreciate it. Thank you for all your help. Need to create a for loop that saves the estimate of pi from each 0f 100 separate iterations and store it in a numeric vector (of length 100). The for loop should be placed in a function that allows the user to vary the sample size, the simulation size,

Dear All, Having now successfully started using Sweave, I have just noticed an odd side effect with fonts. Using plain LaTeX, I have had no problems using \usepackage{palatino} or \usepackage{times} and the font correctly changes. However, once I convert the tex document into Snw, and run it through R CMD SWEAVE, LaTeX seems to ignore this package directive. The LaTeX log suggests the font

Is it possible to produce the same graphic in different formats in one shot? Now if I want to produce the same graphic in pdf, ps and jpeg I run the producing code, but I change the graphic device, and I choose successively : pdf(...) ps(...) jpeg(...) So in this case I run the same code 3 times, or I have to choose a format and use converters... Is it possible to produce the 3 graphics in once

Dear all, I haven't seen this mentioned and presumably Dr. Deepayan Sarkar is too polite to advertise! I just received a flyer from Springer: A new book on Lattice released today!! http://www.springer.com/statistics/computational/book/978-0-387-75968-5?cm_mmc=NBA-_-Apr-08_UK_1753460-_-product-_-978-0-387-75968-5

Dear all, I have been stuck on this problem, am rather struggling and would appreciate some advice if anyone can help. I apologise if this is a bit long-winded, but I've tried to limit it to the bare essentials, but don't know how to make it more generic! I have some slightly odd real world data that I'm looking at representing number of positive diagnoses for different diseases,

Dear All, Writing sooner than I thought I'd need to. I'm using R 2.4 on Mac OS X, with RODBC, PostgreSQL 8.1 and Actual's ODBC driver. I have all my data in Filemaker 8.5, but it is automatically exported into PostgreSQL for analysis as Filemaker's ODBC and JDBC access is awful, slow and has a tendency to crash. I have disability data where for each patient there is a survival

Dear all, I'm using the "survival" package with R 2.4.0 on Mac OS X 10.4.8. I have two core statistics books (one of which is Altman's medical stats book) which suggest showing the number of individuals at risk at different time intervals on the Kaplan-Meier curve. My plot shows two curves that later cross, because of one significant outlier. I have two queries: Is there an

It seems that Access needs that you surround the dates with a # symbol. You probably need something like. res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos' and competitor = 'delta' and dd = #2007-11-20#") Hope this helps, Stefano -----Messaggio originale----- Da: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]Per

Since we're on the topic of book reviews, I just received Phil Spector's new R book called "Data Manipulation with R" and it is also quite a nice book. I haven't gone through it all and I won't give a detailed review but I have gotten a lot out of the first 100 pages that I have read. Note that I've been using R for almost 1.5 years so , for me, it's a

Dear R-users, I have created a bunch of R scripts that automatically create multiple plots, all saved in a pdf device. I initially chose pdf output in order to easily access to multiple plots in a single file. Now, I am trying to play with different devices, like png or eps and I realize that the settings I used to have nice plots in a pdf device are giving awful outputs with the other

Hello all, I'm trying to modify a single column of a data frame to remove randomly half of the values. I want to do it within a function, but can not assign the modified column back into the data frame. It was easy and successful without a function, so I suspect the problem is the call of the single column within the function. removedata<-function(datafull,var.removed) { attach(datafull)

Hi there! To make a good choice for the estimation of the number of usefull factors. And I'd like to plot a graph like: http://de.wikipedia.org/wiki/Bild:Parallelanalyse.jpg where I don't need the green line (random values). But with str(factanal(data, factors=10)) I cannot figure out where I can find the values for plotting. Can you please help me in this question? Thanks, Martin
