HI Everybody Does anyone know of documentation about different ways of obtaining user input in R. I have used readline() but I wondered is there are sophisticated packages that does things like validate answers or generate selection lists. bets regards Christaan [[alternative HTML version deleted]]

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's

Hello, I've recently discovered a persistent issue with rpanel when running R.app (2.6.1) on Mac OS X 10.4.11. tcltk and rpanel load without any apparent error, and the interactive panels appear to work as expected, however upon closing the panels rpanel has created I get catastrophic errors and R crashes completely. For the most part R manages to crash with dignity and work can be saved, but

Hi All, I have created a simulation that works perfect and I have the results been returned in a list as I have multiple values. I then decided to include some user interaction by using the package rpanel, I now get the error: object of type 'builtin' is not subsettable when I attempted to have the return my list with the results . Any help needed. I can also upload code if needs be.

I am working on the r panel package. Now if i have a function that uses a radiogroup button, and if i attempt to run the function from inside the rpanel menu, i get this error: Error in panel$intname : $ operator is invalid for atomic vectors However if i run the function per se i.e. not from inside the rpanel menu, but by calling it independently, the above error doesn't appear. Here is a

I'm sure this is a really simple problem, but I've spent hours digging and I keep running into roadblocks. I'm trying to get a simple chart with three time series. Similar to the attached example http://www.nabble.com/file/p25398419/Excel%2Bchart%2Bexample.pdf Excel+chart+example.pdf , something that was quite easy to do in Excel, except that I need a log y-axis: something that R

Hi all (again), many thanks for the answer to the optimization problem. All is fine now. The problem now is with kernel estimators in sm. package. I do all the work and the graphics good, but I need the density function data for each point, and I don't know how to get it. The only thing I get is the table at the end of the following sequence: >

Possibly of limited use to the original poster, but of interest more generally, there are a number of tools developed in the 70s for updating the matrix decompositions. There's at least one in my 1979 book "Compact numerical methods for computers" (still in print apparently) -- we didn't have enough space to keep all the data in the HP9830A machine. If there's sufficient

I am trying to build an easy to use climate data analysis tool kit that will let non-R users run my detailed r script with minimum R learning curve effort. Here's an example: link <- "http://chartsgraphs.wordpress.com/files/2010/01/nsidc_trend_plot_2.doc" source(link) This lets user run my R script stored at site 1 and work with data stored at site 2 without having to worry

I am getting an unexpected gap in a simple plot of monthly data series. I have created a csv file of monthly climate observations that I store on-line. When I download the csv file and plot one of the series, I get a gap even though there is data for the missing point. Here is a snippet to show the problem. ## Strange plot results link <-

Dear R helpers, I have a question regarding wordpress and R. I have asked this question in Wordpress support ( http://wordpress.org/support/topic/368312 ) but there is no answer so far, maybe the R community can have a better answer. I followed the excellent tutorial on r-statistics-blog ( http://www.r-statistics.com/2010/02/r-syntax-highlight-on-your-blog-a-wordpress-plugin/ ) to enable syntax

Hi all, In R, is there some functions or ways to create a Clustered-Stacked Column Chart as the example in the following page http://peltiertech.com/Excel/ChartsHowTo/ClusterStack.html? I have browsed the R Graph Gallery (http://addictedtor.free.fr/graphiques/) and searched the R site, and didnot find an appropriate method to do it. Anybody has met this problem before? Thanks a lot.

HI R users, I would appreciate information/examples/suggestions on building GUIs for R applications. I am currently working on a project that would require the following functionalities : 1) Display a window to the user. Provide a function to scan local drive and choose dataset file. 2) Display the column names for the user to choose the dependent variable and the independent variables. 3) Fit

Hi, I need to do some multivariable linear regression from RoR. I have found one possible solution: 1. Install R on my host (Dreamhost) 2. Use the "R for Ruby" gem Using a complex statistical package such as R seems a bit complicated however, and I am wondering if you would have a simpler solution ? The data is gathered online from the user, stored in the mySQL database, and I need

The pretty picture that I saw at: http://chartsgraphs.wordpress.com/2009/02/09/r-panel-chart-beats-excel-chart/#more-1096 inspired me to try something similar. The code that I wrote is: ------snipsnip--------------------------------------------------------------------- M <- structure(list(date = structure(c(13634, 13665, 13695, 13726, 13757, 13787, 13818, 13848, 13879, 13910, 13939, 13970,

Comparto totalmente la sugerencia de Carlos Ortega. Si aún así quieres gráficos de velas o gráficos OHLC el mejor paquete que puedes usar es uno de temas financieros: http://www.quantmod.com/ Ten en cuenta que en los mercados bursátiles tiene algún sentido usar ese tipo de gráfico ya que en la apertura y mayormente en el cierre diario se concentran operaciones. Me imagino que esto no es así con

Hi all, A friend just sent me this: http://www.mathworks.com/company/events/webinars/index.html?id=&language=en <http://www.mathworks.com/company/events/webinars/index.html?id=&language=en>And asked me if there is something of the like in the R community. Does anyone know of such a think ? Cheers, Tal ----------------Contact

I have a population of subjects each with a variable which has been captured at a baseline date. Then for many subjects (but not all) an intervention has occurred and the variable has changed at one or more time points after the baseline date. So my dataset consists of a subject ID (x), which may appear several times or just once, a measure (y), and a date of observation (z). I would like to be
