Hi, I am trying to understand the building of Huffman codes from the code lengths. In the Tremor code first I see that the codewords are being generated by the function _make_words() and then sorted. After this I see some magic code and something related to unused entries. Does the code generate code words for unused entries too? Are these unused entry code words used during the decode

Greetings, This, I hope, is a simply answered question. Based on Agile Web Development with Rails (depot application), I''m developing a single table application for contact info.

Dear All, I usually work with time series data. The data may come in AM/PM date format or on 24 hour time basis. R can not recognize the two differences automatically - at least for me. I have to specifically tell R in which time format the data is. It seems that Pandas knows how to handle date without being told the format. The problem arises when I try to shift time by a certain time. Say

If anyone wants to see a prime example of how inefficient it is to program in SAS, take a look at the SAS programs provided by the US Agency for Healthcare Research and Quality for risk adjusting and reporting for hospital outcomes at http://www.qualityindicators.ahrq.gov/software.htm . The PSSASP3.SAS program is a prime example. Look at how you do a vector product in the SAS macro

I have a really long functions, and at the end of the function, I am using a if statement to tag certain keywords based on whether they have certain values contained in them. However, the if statement doesn't seem to work. When I had split up the commands into various functions, it worked fine, but I'm not sure what going on now that it's combined into a single function. myfunc
