Dear list, first accept my apologies for asking a non-R question. Can anyone point me to a good reference on logistic regression? web or book references would be great. I am interested in the use and interpretation of dummy variables and prediction models. I checked the contributed section in the CRAN homepage but could not find anything (Julian Faraway?s "practical Regression and ANOVA

Dear list, this must be an easy one: I have a data.frame of two columns, "ID" with four different levels (A to D) and numerical "size", and each of the 4 different IDs is repeated a different number of times. I would like to get the mean size for each ID as another data.frame. I have tried the following: >ID= as.character(unique(data[,1])) # I use unique() because

Dear list Is there anywhere I could find further information on how to interpret the output for a logistic regression for validate() from Design package?. I tried ?validate and google but I cannot find information on what the rows and the columns represent. Thanks David

Dear list, first apologies for this is not strictly an R question but a theoretical one. I have read that use of k-means clustering assumes sphericity of data distribution. Can anyone explain me what this means? My statistical background is too poor. Is it another kind of distribution, like gaussian or binomial? What does it happen if the distribution is not spherical? Could you give me an

Dear list, I have a data.frame with nine categorical variables (0,1,2 and NAs) that I would like to get the number of events for each of them. I can extract this using summary() for each variable at a time with the as.factor()argument (otherwise it will get me the mean value): >summary(as.factor(mydf[,3])) 0 1 2 NA's 194 67 4 2 Trying to use apply() to get this for

Dear list, I have a categorical variable in a data.frame that I would like to plot using a histogram to show number of events. Values are 0, 1 and some NAs. I can?t make the hist() function to 1) include a column with the number of NAs 2) have the x axis to be categorical, I always get 0, 0.2, 0.4,... 1 divisions Can anyone help me? This is my code. "database" is my data.frame and

Dear list, I have a text file from a scanner that includes 20 lines of text (scanner settings) before it actually starts showing the readings in a tabular format (headings are ID, intensity, background and few others). I am a biologist with some experience using R and my question is if it is possible to read this file into an R workspace and store the actual readings in a dataframe,

Hi Folks, I'm interested in looking (in a beginner's amateurish way) at prosodic/phonetic analysis of recorded speech. In particular I would want to use R to formulate and evaluate specific models. So I would like to ask R people for their recommendations for a program which would a) Take as input a sound file in one of the common formats (".wav", ".au") b)

I want to make a graph where each element plotted is itself a graph. I can see how to use par(fig=) and viewport to do that, but they require (i think) me to do my own scaling as they are scaled to the graphics window. any advice on which approach I should take (just bite the bullet and do my own scaling), or is there something else I should try, or any examples I should look at. many thanks

I'm following up on a thread started by Stephen a couple months ago about building a JavaScript source client using webrtc. The first step suggested was to figure out how to mux the audio and video. After I posted a feature request on the webrtc experiment js library, we seem to have a solution: https://github.com/muaz-khan/WebRTC-Experiment/issues/28#issuecomment-20791759 Based on the last

Hi Folks, I'd be grateful for some views on the following. When I say "plot y against x" I mean that y is on the vertical axis and x is on the horizontal axis. I acquired this usage so long ago that I can no longer remember how I acquired it, and therefore can not cite my "authority" for my usage. There can also be an implication that y is a function of x (or y is a

Hi list, hi John, having seen last week a post (see http://marc.theaimsgroup.com/?m=107341768923846) that remind me some quirks I encountered, I'd like to see a preamble added to the chapter 12 of the howto. It concerns the diffent types of admin you will need in a PDC setup. I say preamble, but it could be found anywhere else, as long as it could be found (I have lost long hours

Five years after initially posting to this list[0], I finally completed as browser-based video source client iceast. The code is here: https://gitlab.com/jamie/icecream As Romain Beauxis responded to my initial email, webrtc was unsuitable and websockets was the way to go.

I would like to know if someone has done work on trees with multivariate response. I need something like rpart but for vector responses. If someone has code that he/she is willing to share, I would be grateful. If not, even guidelines for writing my own starting from rpart would be welcomed. ft. -- Fernando TUSELL e-mail: Departamento de

Gracias, Javier, por la paciencia. Soy malo explicándome. Ese ejemplo que me das, que es el que da Yihui Xie, es el que no consigo compilar si no es a GitBook (que es HTML). El mismo Yihui propone en el libro al que nos referimos los dos y el ejemplo en cuestión (referido en el apartado Get Started) modificar el código YAML para compilar en PDF. Efectifvamente, lo que quiero es conseguir que

Según lo entiendo yo, a mí no me funciona. Lo intenté hacer, también, en la consola directamente. Preferiría poder hacerlo en el documento Rmd, pero de momento ni uno ni otro consigo. Si compila lo hace al libro GitBook y listo. Parece imposible. 2018-07-17 20:02 GMT+02:00 Javier Marcuzzi <javier.ruben.marcuzzi en gmail.com> : > Estimado Juan Abasolo > > Yo no lo utilize pero leí
