...egacy database. All is going well (using set_table_name, set_primary_key, etc), but I can''t get my many<=>many relationships to work. My contrived example of the situation: Student has_and_belongs_to_many Teachers. This is mapped via table student2teacher where the foreign keys are studentId and teacherId. The primary key in Student is studentId, and in Teacher is teacherId. However, when I run my unit tests I am getting this error: Mysql::Error: Unknown column ''j.student_id'' in ''where clause'' This is confusing, because I explicity specify that the...

...odel on our data. The outcome variable is binary. I got the error when I wanted to add a group factor to my model. My initial model is as below: model.a <- nlme(response~ 1/(1 + exp( -intercept- u0 - slope*TIME - u1*TIME)), + fixed=intercept+slope~1, random= u0+u1~1 |studentID, + start=c(slope=.01, intercept=-1), data=log.data, method='ML') This works fine on my data. But when i update it by adding a group factor SKILLS, I got the error message: "Error in nlme.formula(response ~ 1/(1 + exp( -intercept- u0 - slope*TIME : s...

More complex version: My data is in this format because it's the output of a "by" statment that looks like this: y <- by(d,list(d$StudentID,d$Assignment),gapfun) (where gapfun is a function I've defined that takes a data frame and returns another data frame). What I would like is to do is transform y into a data frame that has columns "StudentID", "Assignment", and the columns in the data frame returned by...

Hello lmer() - users, A call to the lmer() function causes my installation of R (2.11.1 on Mac OS X 10.5.8) to crash and I am trying to figure out the problem. I have a data set with longitudinal data of four subsequent performance measures of 1133 individuals nested in 88 groups. The data is in long format. I hypothesize a performance increase for each individual over time and intend to

...data with measures nested within child. There are two measures per child. I've fit an unconditional growth model as in Singer and Willet (2003) that allows for variable intercepts and slopes. The R code for the analysis is: model.uncgrowth.2lev <- lme(math ~ grade, mathdata, random=~grade|studentid) The fixed effects estimates for the intercept and slope are the same between MlwiN and R. It's the random effects estimates that differ. In particular, the residual error variance is ZERO using MlwiN and significantly non-zero using R. It appears that MlwiN perfectly fits lines to each of the...

Hi I am trying to convert SAS codes to R, but some of the result are quite different from SAS. When I ran proc mixed, I have an option ddfm=bw followed by the model. How can I show this method in R?(I am thinking that this maybe the reason that I can't get the similar results) below is my SAS codes: proc mixed data=test covtest empirical; class pair grade team school; model score = trt

Dear all, I use lmer to fit a mixed effect model.It give some warnings. What can I do about this?
