Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML

I have a simple query as follows: "SELECT m_id,sale_date,YEAR(sale_date),WEEK(sale_date),return_type,DATEDIFF(return_date,sale_date) AS elapsed_time FROM risk_input" I can get, and view, all the data that that query returns. The question is, sale_date is a timestamp, and I need to call split to group this data by m_id and the week in which the sale occurred. Obviously, I would

Hi,everyone i need to calculate quartile values of a variable grouped by the other variable . same as in aggregate function(only median,mean or functions is possible-i think so) Could you please help me to achieve the same for other quartile values(5,10,25,75,90) as for median using aggregate.

My last query related to this referred to a problem with not being able to store data. A suggestion was made to try to convert the data returned by fitdist into a data.frame before using rbind. That failed, but provided the key to solving the problem (which was to create a data.frame using the variables fitdist produces in the object it returns). I now have almost everything working as

I'm interested in computing densities of a number of small ego-centred or local networks. I've installed both the R program and the sna package. My next task is importing the data into R. Our data was entered into Spss in an edgelist format in which each case specifies the link between an alter and an ego. For example: 10101 10102 1 10101 10103 3 10102 10104 2 10201 10203

I must have missed something simple, but still, i don't know what.

I want to make you aware of a possible bug in the reflink handling of btrfs: When I reflink a file larger 2GB (on the same subvol), the reflinking fails. But it works fine for files smaller 2GB in size. I was able to track this down to btrfs with great support of Martin Raiber who created a small demo code: Source: https://urbackup.atlassian.net/secure/attachment/10201/reflink.cpp Compile: g++

Hi, I have the panel data of income statement of several banks. The date 9803 means 1998-Q1, 9806 means 1998-Q2, etc. I transform the date code to 1 (for 1998Q1), 2 (for 1998Q2), ...., 16 (for 2011Q4) where 1, 2, .... are placed in Col1. Now the income statement of a specific quarter is actually the accumulation from the beginning of the year. For example, the cost data of 1999Q3 is the
