Hello, all, We're now starting to cover hypothesis tests in my Stats 101 course. As usual in courses using the Lock5 textbook, 3rd ed., the homework answers are calculated using their StatKey application. In addition (and for no extra credit), I'm trying to solve the problems using R. In the case of hypothesis test, in addition to manually setting up randomized null hypothesis

Hi, Rui and Michael, thank you both for replying. Yeah, I'm not supposed to know about Chi-squared yet. So far, all of our work with hypothesis tests has involved creating the sample data, then resampling it to create a null distribution, and finally computing p-values. The prop.test() would work. obviously. I'll look into that. I didn't know about it. I'm really struck by the

Daniel, muchas gracias por contestar y tan rápido. Pues puede ser la solución, he hecho el cambio y sigue sin pintarme los puntos -> data_ <- toJSONArray(data_, json = F) map$geoJson( # leafletR::toGeoJSON(data_, # # lat.lon = c('Lat', 'Long'), # dest=output_geofile), data_, onEachFeature =

So im here now b/c im incredibly frustrated. Please consider the following: #Try 1 Data_<-list() Sn<-1:12 for(sn in Sn){ for(i in 1:10){ Data.X <- rnorm(100,0,10) Data_[[paste(sn,i,sep="-")]]<-Data.X } } ##Try 2 Data_<-list() Sn<-1:12 for(sn in Sn){ for(i in 1:10){ Data.X <- rnorm(100,0,10) Data_[[sn]][[i]]<-Data.X } } In Try 1 i am able to append

hi all I am using r (2.15.2) in windows 7 32bit I want to execute an external program from r console. the program is a command line program which needs the following format to start C:/Users/.../dssp-2.0.4-win32.exe -i data_1.txt -o data_1.dssp I used the system command as: system ('C:/Users/.../dssp-2.0.4-win32.exe -i

Hola, Ando un poco desesperado con los mapas interactivos de Rcharts <https://github.com/ramnathv/rCharts>+Leaflet. Estoy intentando pintar en un mapa las cámaras de tráfico de madrid, y las estaciones de calidad del aire, simplemente donde están, es decir, aun no estoy recogiendo los datos de medida.

How about calculating a 95% confidence interval about the estimated proportion in favor. The PooledInfRate package will do this for you. If confidence intervals overlap then there is no significant difference. -----Original Message----- From: R-help <r-help-bounces at r-project.org> On Behalf Of Kevin Zembower via R-help Sent: Saturday, March 29, 2025 12:10 PM To: R-help email list

Hello, I'm trying to create a data frame with three columns, one of which is a variable-length list. I tried: df <- data.frame(name = c("a", "b", "c"), type=c(1, 2, 3), rtn = c(list(1,2,3), list(4, 5,6), list(7,8,9, 10) ) ) This would be useful, for example, if the 'rtn' is a variable number of

Dear R community, I wish to include a variable (e.g. slice of "a" below) in another variable's name. My objective would be to get a variable-name "data_A" and so on. How can I do this? > a<-LETTERS[1:25] > a [1] "A" "B" "C" "D" "E" "F" "G" "H" "I" "J"

Thanks David. I meant to send to lldb maillist, but glad to hear response here. Our binary is built from gcc: String dump of section '.comment': [ 1] GCC: (GNU) 4.9.x-google 20150123 (prerelease) Is there any similar flags we should use? By doing "strings -a [binary] | grep -i gcc", I found the following flags being used: GNU C++ 4.9.x-google 20150123 (prerelease)

Dear helpers, In an attempt to use a loop to generate graphs in a for loop in run into a problem. The plan is to fill each page with eight graphs (mfrow = c(4,2)) in to two columns. Only the buttom graphs ( meaning every fourth graph) have tick labels on the x axis to preserve space. I used an if .... Else statement to achieve that. The problem is that the first eight graphs are skipped

Dear all I am using r (2.15.2) under windows 7 32bit. I want to use system command to execute an external program inside a for loop. this program needs the input and output names. since the names will change in the for loop I am not able to use the programs on all the files for (k in 1:10){ x=read.table ("data.txt") xx=x[1:5, ]

R-helpers: I'm sure this question has been asked and answered through the ages, but given there are some new textbooks out there, I wanted to re-pose it. For a course that will cover the application of R for general computing and spatial modeling, what textbook would be best to introduce computing with R to *undergrads*? I understand Bivand and Pebesma's book is fine for spatial work,

We just studied randomized block design analysis in my statistics class, and I'm trying to learn how to do them in R. I'm trying to duplicate a case study example from my textbook [1]: > # Case Study 13.2.1, page 778 > cd <- c(8, 11, 9, 16, 24) > dp <- c(2, 1, 12, 11, 19) > lm <- c(-2, 0, 6, 2, 11) > table <- data.frame(Block=LETTERS[1:5], "Score

Monte, For a list of online sources that may be useful, go to http://www.uvm.edu/~dhowell/methods/Websites/Archives.html and check out some of the material referenced there. Clay Helberg's site is particularly helpful. Unfortunately it is virtually impossible to keep links current, so some are likely to be dead--although you can often find them via Google.

Hi, I know this is a little bit offtopic on this list. But I can't find a more appropriate forum that I can ask. If there is a high quality forum on statistics textbook discussion, please let me know. I am reading Applied Linear Statistical Models. One drawback that I feel about this book is that it discuss many examples, which is to distracting. Numbers are give in those examples. Comments

Dear Lists, I got the chance to review Bob Muenchen's book - R for SAS and SPSS users. While my detailed review is online at www.decisionstats.com, the book is a welcome addition in R Textbooks for beginners and an especially nice one for people who have experience in SAS and /or SPSS languages. AT 50 USD, it's reasonably priced for all geographies (;) , and quite handy as a refernce book
