similar to: How to fix false positve rates?

Hello R-USERS, I think some people didn't understand my question. What I want is to use the training set to minimize the FALSE POSITIVE RATE. I think it is possible. I sacrifice ACCURACY to have less FALSE POSITIVES. I don't want a classifier result with 5% of FPR and, for example, 93% of ACCURACY. I want a 1% FPR sacrificing the 93% ACCURACY. Do you know how can I do this? I really

How to plot multiple variables on the same graph Dear R users, I want to plot the following variables (a, b, c) on the same graph.

Hi I am facing a problem where I would like to import a TIFF image (of spots on a nylon filter) into R (into a matrix for example). When plotting the matrix using fx. scatterplot3d I would then be able to see how the pixel-intensities are distributed in "spot-areas" on the filter - which would be very helpful. Does anynone know of a way to do this? Best regards, Peter Hagedorn ...

Hi All, I have been researching Asterisk for a few days now and have read hundreds of web pages and other documents. While some things are getting clearer, others are not. I have managed to install Asterisk 1.0.1 on Debian testing (simple as 'apt-get install asterisk'). I understand FXS/FXO, codecs available, feature and functionality available etc. I have found several "Getting

Hi, When we use OP_ELITE_SET we can specify the number of terms we want to use. In http://trac.xapian.org/wiki/FAQ/EliteSet there is this text: "The number of terms which OP_ELITE_SET will use defaults to 10 (or ceil(sqrt(number_of_subqueries)) if there are more than 100 subqueries), but may be set by specifying a parameter to the query constructor" is it possible to use only the

Hi, I'm experiencing problems when doing phrase searches with adjacent repeated terms. Example: if I search for 'curtain curtain' and there are documents that matches the query, they aren't returned. But, if I search for 'curtain nice curtain' and there are documents that matches this query, it works ok. attached there is a python program that shows the problem. I tried
