similar to: Invoking bond_prices function of termstrc package

Hi, I'm trying to use the package termstrc. However I cannot figure out how to invoke helper functions like create_cashflows_matrix & create_maturities_matrix. Even when I try to invoke those with the data supplied with the package (say, corpbonds), it throws error saying "Error in as.vector(x, mode) : invalid 'mode' argument".

Any file

Hi, We have couple of places which can result in deadlock. This patch series fixes these. We can be called with fc->bg_lock (for background requests) while submitting a request. This leads to two constraints. - We can't end requests in submitter's context and call fuse_end_request() as it tries to take fc->bg_lock as well. So queue these requests on a list and use a worker to

Hello, Could anybody offer any advice about implementing a Kohonen self organizing map for categorical data? Specifically I am wondering if there are any pre-existent packages that can deal with categorical data and/or how one would compare the input vector of categoricals with the self organizing map nodes.
