Greetings List, I'm having some trouble with the use of the names function in a formula. Below is an example of something that works (i.e first line), and the second line is the same formula which doesn't. I want to be able to reference the column of the dataC table so I can run the variogram iteratively with a loop. > v<-variogram(A1~1,loc=~x+y, dataC) >

Hello, I am running Kruskal-Walis test in R. When I try to save results using write.table it gives me the following error : Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) : cannot coerce class "htest" into a data.frame The overall code is as follows : >data_file = read.table("~/DATA.dir/data_file.txt", header=T)

Hi R-helpers, I have been struggling with calculating row and column statistics, e.g. standard deviation. I know that > datac$Mean<-rowMeans(datac,na.rm=TRUE) will give me row means. I have tried to replicate those row means with the apply function: > datac$Mean2<-apply(datac,2,mean) so that I can replace the function argument with "sd" (instead of mean) to get standard

Hi all, I am trying to fit t distribution using the function "tFit" in the library(fBasics). I am using the code tFit(datac[[2]]) and it returns the following list. Title: Student-t Parameter Estimation Call: tFit(x = datac[[2]]) Model: Student-t Distribution Estimated Parameter(s): df 78.4428 I just wonder how can I refer to the estimated parameters. I tried

Dear All- I am trying to merge two data files - they have different date formats and different times zones. I need to match up the date/time of the datasets and then invoke a conditional statement, such as: if dataC$mph is >= 12 then keep dataM$co23 for the corresponding time/date stamp. snippets of data files: *dataC.txt* LST in mph Deg DegF DegF2 % volts Deg

hello list, i'm a bit puzzled by the error message i get when i copy past this in R:

I am working with some survival data with missing values. I am using the mice package to do multiple imputation. I have found code in this thread which handles pooling of the MI results: https://stat.ethz.ch/pipermail/r-help/2007-May/132180.html Now I would like to plot a survival curve using the pooled results. Here is a reproducible example: require(survival) require(mice) set.seed(2) dt

Hi, I am relatively new to R; when creating functions, I run into problems with missing values. I would like my functions to ignore rows with missing values for arguments of my function) in the analysis (as for example is the case in STATA). Note that I don't want my function to drop rows if there are missing arguments elsewhere in a row, ie for variables that are not arguments of my

Hi, I used to use reshape and moved to reshape2 (R 2.15.1). Now I tried some of my older scripts and was surprised that my cast function wasn't working like before. What I did/want to do: 1) Melt a dataframe based on a vector specifying column names as measure.vars. Thats working so far: dfm <- melt(df, measure.vars=n, variable_name = "species", na.rm = FALSE) 2) Recast the

Hello, I have some code that currently works fine and I am endeavoring to convert the major pieces of it into functions. This involves taking "hard coded" names of variables that are used in various places and figuring out how to abstract them out into functions where the arguments (i.e. a list of variables)?can be passed to the parent function and used within that function for various

I found the post about needing to install acts_as_attachement_1_1_6 if you are not on edge rails. But I am having trouble getting db_system storage to work. As far as I can tell in from the database, things are working, but I don''t see how my model table hooks up with the db_files table so I am having trouble altering the image_tag from the tutorial

Hi There, I get the following error from the code pasted below: Error in storage.mode(test) <- "logical" : object 'HGBmt12_Natl_Ave_or_Facility' not found library(RODBC) library(car) setwd("c://temp//cms") a07.connect <- odbcConnectAccess2007("DFC.accdb") sqlTables(a07.connect) ##provides list of tables## dataset <-

Hi all, Tried out the mongrel upload progress plugin with Drb and it works great on my OSX development box, but when putting it into production (Ubuntu Dapper), uploads complete but the app isn''t returning any values for upload progress, and uploads are not showing up in the queue when running upload_client.rb. Before anyone asks, yes, I''m running both the mongrel instances and

Hello, I've been struggling with a problem for the past several weeks, trying to get PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) to work on Red Hat 9. In brief, R dumps core during the embedded library initialization, while in Rf_regcomp(), working on on Rprofile. Below I've included the important parts of a backtrace: Program received signal

Greetings everyone, I was wondering if anyone had experience in using fda (flexible discriminant analysis) in the mda package. Specifically, I can run the model but I cant locate/produce much of anything beyond the predicted values and confusion matrix. I've been searching for more examples or documentation but cant seem to locate any specific to the program itself. I need to be able to find

Hello, Have anybody a hint, how I could iterate over the vector below. So I'll wish only 8 iterations. Put the "range vector" in c() didn't help. for(i in c(1,2,3,4,5,11:20,21:50,51:100)) { sum(dfc[i,"cnt"]) # or similar actions } Thanks in advance Christian

Full_Name: Roland Puntaier Version: 1.8.1 OS: Windows XP Submission from: (NULL) (62.99.238.78) I have a data frame with some columns being logical. I wanted to calculate a column that is an AND combination of the other logical columns. I tried to use apply(df,1,all) It did not work because of the implicit string conversion. So I made the functions All<-function(...)

Hello, I have a written a couple of functions (states.trends(.) and trend.generator(.)) to create monthly aggregated time series from disaggregated data.
