Dear All, I apologize for this trivial question, I can not find the solution I try to use t.test function per line in the data.frame, But i dont'understand the error message my program is as follows group1<-gl(2,20) fun<-function(x){ m<-data.frame(group1,x) #anova(aov(x ~ group1, m)) t.est(x ~ group1,m) } ttest<- apply(data, 1, fun) Error in t.test.default(x = c(1, 1,

Hi all Assume I have a data set xx; Group: 1=group1 ?, 2=group2 IQ: ?1= High, 0 =low fit <- glm(IQ ~group, data = xx, family = binomial()) summary(fit) Results ?????? ????????????Estimate Std.

hi R gurus I saw some graphs with vertical band like this one: http://pragcap.com/wp-content/uploads/2010/04/GS.png how to draw the blue band in R, can't find any clue to do this,any ideas? thanks in advance [[alternative HTML version deleted]]

Dear All, I have matrix (50000 X 60) of subjects and their responses to a set of questions. All responses are classified into categories (500). I would like to average all subject's responses for each category. I wrote a code using a for loop but is not working. Could please tell me what's wrong with the code? I guess, there is a elegant R way of doing the same thing. Thanks in advance.

Dear Friends, Yesterday I posed a question to the list concerning the possibility of doing animation examples in R. Here is an example S-Plus (4.5 for Windows ) that I wrote to illustrate my problem. If I try this in R (comment out the graphsheet and guilocator calls) I don't see my results until after the function has iterated through the 100 trials. I would like to plot each iteration.

Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

Dear All, I am not very into object-oriented programming, but I would like to learn the ropes for some R applications. Quoting from the online R language definition (paragraph 5.1) > Consider the following simple example. A point in two-dimensional > Euclidean space can be specified by its Cartesian (x-y) or polar > (r-theta) coordinates. Hence, to store information about the location

Hi, I''m having a dataframe ''Subset1'' with a number of factor variables and 160 numerical variables Now I want to make sums for all rows that have the same values for the different factor variables, except for the factor variables: VAR1,VAR2,VAR3 who may have the same values. With the formula given below this works great, but in a situation with 15000 rows and 13

Dear r-help, Could you help me to find a solution for this error: Il y a eu 50 avis ou plus (utilisez warnings() pour voir les 50 premiers) > warnings() Messages d'avis : 1: In if ((data[pa, k] == df[, j]) & (data[ch, k] == i)) { ... : la condition a une longueur > 1 et seul le premier élément est utilisé 2: In if ((data[pa, k] == df[, j]) & (data[ch, k] == i)) { ... : la

Hi, I'm looking for the way to make vector plot over a time line. This plot, similar to the "feather plot" in Matlab, is a line in which every thick (a time value) one vector is drawn with its length proportional to one variable (wind speed, for example) and its direction to another (wind direction, for example). Any ideas? Thanks, EKS -- ---------------------------- Eduardo
