Hi all, I tried to do a variance components using nlme, but I got the following warning mesage ##################################################### not meaningful for factors in: Ops.factor(y[revOrder], Fitted) ###################################################### Can someone point out what is the meaning of this warning message? I tried to look at Ops.factor, but I don't

Hi all, If I want to write a for loop to loop through a set of factors, which are not coded in 1,2,3, for e.g in character, possible to write the for loop without changing it to categorical variables? I saw the manual mentions for loop will take a list, but I'm not sure how to create a list here. Any input will be appreciated. Thanks. Yen Lin [[alternative HTML version deleted]]

Hi all, I wonder how could I convert a matrix A to a dataframe such that whenever I'm running a linear model such lme, I can use A$x1? I tried data.frame(A), it didn't work. Should I initialize A not as a matrix? Thanks. Yen Lin [[alternative HTML version deleted]]

Hi all, I just wonder what singular convergence means. Thanks. Yen Lin Error in lme.formula(Data ~ 1, random = ~1 | Wafer/fie/loc, subset = Wafer == : singular convergence (7) [[alternative HTML version deleted]]

Hi all, Does lme has function to compute the cook's distance or influence measure like lm? I can't find them. Thanks. Yen Lin [[alternative HTML version deleted]]

Hi all, I have read a data matrix of 304 x 404 using read.table. When I am trying to name the colnames, with first try colnames(L5)<-list(2:305), I keep getting error message such as Error in "colnames<-"(`*tmp*`, value = list(c(2, 3, 4, 5, 6, 7, 8, 9, : length of 'dimnames' [2] not equal to array extent and I don't know why. But, if I look at

Hi I would like to learn how the R function "hclust" deals with ties. It is written in Fortran, so I cannot access the code. Thanks!! [[alternative HTML version deleted]]

Hi all, I am a bit confused when i type rake spec and it gives me this message, No examples matching ./spec/**/*_spec.rb could be found what is that mean that something is not found. and where i can input my the test code because i did have a tiny sample code in user_controller_test.rb. is that the right place to test functional.. plz give me a help thanks -- You received this message

Hello, everyone, There's a problem about zero in R and I really need your help. I have a vector shown as x=c(0.1819711,0.4811463,0.1935151,0.1433675), The sum of this vector is shown as 1 in R, but when I type 1-sum(x), the value is not zero, but -2.220446e-16. I can accept that this value is quite small and could be seen as zero, but there would be a problem when it's not really

is there a way to do element-by-element multiplication as in Gauss and MATLAB, as shown below? Thanks. --- a 1.0000000 2.0000000 3.0000000 x 1.0000000 2.0000000 3.0000000 2.0000000 4.0000000 6.0000000 3.0000000 6.0000000 9.0000000 a.*x 1.0000000 2.0000000 3.0000000 4.0000000

Dear All I inserted a frequently used function (subroutine) right into my Rprofile.site which allows me to run it each time-works great. However, this approach is obviously suitable for a short function or a small number of functions. Instead of inserting the lines in Rprofile.site, is there a way to insert one line pointing to (fetching) the function in a local drive, similar to #include

Hello everyone, I have been working on a code which simply repeatedly appends a number into a vector and write a file. However, it could not be properly implemented when I use it. It works when I run it line by line. I wonder what is the problem and I appreciate anyone who is willing to help. The function and the example code is attached. Any advice is appreciated! Best, Yen

The RStudio list generally does not respond to free version users. I was hoping someone one this (R) list would be kind enough to help me.

Hello dear uesRs, I am working on modeling both level one and level two heteroscedasticity in HLM. In my model, both error variance and variance of random intercept / random slope are affected by some level two variables. I found that nlme is able to model heteroscedasticity. I learned how to use it for level one heteroscedasticity but don't know how to use it to model the level

Hi, Just a quick question. I wonder if the package of "car" has been removed from the most current version of R. Or what can I do to renew it since I have to do the analysis with that? Thanks, yen

Thanks for the help. I have a reason to continue with R-3.0.3. I used maxLik to estimate econometric models and some of them are better handled with R-3.0.3 (but not later)----a sad reality I do not like. Here is what I did. I downloaded https://cran-archive.r-project.org/bin/windows/contrib/3.0/aod_1.3.zip and installed the zip file, which worked in both RStudio and R (without RStudio). In

Hi, I am using the Strucchange package in R to test for structural change in regression coeffcient. Given a model y = b0 + b1*X + b2*Z, the Fstats test whether there is a change in both b1 and b2 over a time period. Is there any way where I can restrict the test to hold b2 constant and test for break in only b1? That is, instead of a pure structural change, could I test for partial structural
