similar to: AOV() may misslabel random effects.

First, I compliment you all for such a useful project as R. Suggestion: If read.table() could take input from a character string, then one could write raw= " x y z 1 2 3 4 5 6 " df = read.table(raw,head=TRUE) Of course, one can cat() to write raw into a temporary file, and read.table() from that file. However, direct reading might be a good option? Hope this is

Dear Colleagues, John Mandel ( Chain block designs with two-way elimination of heterogeneity. Biometrics 10, 251-272 ,1954). extended the class of chain block designs (Youden & Conner (1953) to elimination of both row and column (blocks) effects. These experimental designs can be useful in engineering and other fields. I am having difficulty obtaining his adjusted treatment means in his

When enabling user homes (via the [homes] section), I see the following shares: \\server\<username<http://>> \\server\homes<http://> Both of which point to the user directory. Is it possible to have a third: \\server\home<http://> Which does the same? \\server\homes<http://> is great and all, but I feel that the plural is a bit of a mislabel. Shak

Full_Name: Marek Ancukiewicz Version: 0.64.0 OS: Linux (RedHat 6.0) Submission from: (NULL) (132.183.12.87) I've noticed that factor structures get recoded when the data is dumped using either dump or dput and then restored with source or dget. This occurs when the values taken by factors do not include 1. For example: a <-

Hi useRs, A recent coding infelicity along these lines yielded a corrupt data frame. foo <- matrix(1:12, nrow = 3) bar <- data.frame(foo) bar$NewCol <- foo[foo[, 1] == 4, 4] bar lapply(bar, length) > foo <- matrix(1:12, nrow = 3) > bar <- data.frame(foo) > bar$NewCol <- foo[foo[, 1] == 4, 4] > bar X1 X2 X3 X4 NewCol 1 1 4 7 10 <NA> 2 2 5 8 11

There are instances when assignment should be indicated by "<-" rather than "=". One example is the function Sys.time(). sytem.time( x=1:10000) # x is interpreted as an argument and is an error here. system.time( x<-1:1000) # times the creation of x with numbers 1 to 10000 However, grouping the statement with curly brackets also gives the correct system time.

Greetings. How can I insert gridlines in the following density plot call? Must one compose a panel function? 'data.frame': 46 obs. of 2 variables: $ fallrates: num 5.2 7.1 7.1 9.8 3.7 7.5 5 6.2 1.5 2.9 ... $ prepost : Factor w/ 2 levels "post","pre": 2 2 2 2 2 2 2 2 2 2 ... library(lattice) densityplot(~fallrates, groups = prepost,

Colleagues: I am having trouble loading data from within .Rdata file within the environment of a function. That is, the following always loads to the global environment: f1 <- function() { load("mydata.Rdata") # compute with objects from mydata.Rdata. } I wish to load mydata.Rdata only within the function f1. Perhaps I have misunderstood

Surprising behavior: Most R users are aware that print() must be used inside functions to gain output on the console. Apparently, print() is sometimes required when interactively using the console. For example, the followingmay be entered into the R console with different results. sample(1:8,8) #prints a permutation of 1 to 8 for(i in 1:5) #does not sample(1:8,8)
