Dear Members of Xapian Project, Sorry for troubling you this time. I am currently facing a challenge that I can not search and update Xapian "InMemoryDatabase" concurrently via 2 different threads although I have added the critical area mutex which allows only reading/writing at one single time. More specifically, along with the core dump, the error message was "double free or

Dear Members of Xapian Project, Sorry for troubling you this time. It can be witnessed that xapian will store Document values with serialization approach when given value types meet float/double. Such an approach is deployed on sort_key related fields as well, where the xapian requires KeyMaker::operator() must return an serialized float/dobule variable. Then heap sort comes and ranks

I'm getting the following error when trying to build xapian. I've tried versions 0.9.1 and 0.9.2, same error. It's a x86 debian box, gcc 4.0.1. It builds fine on my gentoo amd64 box (gcc 3.4.3).

Hi jpm miao, You can get CSV files that can be imported into Excel like this: library(prettyR) sink("excel_table1.csv") delim.table(table(df[,c("y","z")])) sink() sink("excel_table2.csv") delim.table(as.data.frame(table(df[,c("y","z")])),label="") sink() sink("excel_table3.csv")

Hi, I conduct a panel data estimation and obtain estimators for two of the coefficients beta1 and beta2. R tells me the mean and covariance of the distribution of (beta1, beta2). Now I would like to find the distribution of the quotient beta1/beta2, and one way to do it is to simulate via the joint distribution (beta1, beta2), where both beta1 and beta2 follow t distribution. How could we
