similar to: Fwd: I need help with an R function! Thx!

Hi, I am new to R so I would appreciate any help. I have some data that has passenger flight data between city pairs. The way I got the data, there are multiple rows of data for each city pair; the number of passengers needs to be summed to get a TOTAL annual passenger count for each city pair. So my question is: how do I create a new table (or data frame) that selectively sums My initial

Hi All, I have a data set containing : pclass: A factor giving the class of the passenger: one of 1st, 2nd, 3rd. age The age of the passenger in years. sex Passenger's gender: female or male age.group Passengers age group, one of 0?9 , 10?19, 20?29, 30?39, 40?49, 50?59, 60?69, 70?79 survived Passenger's survival (1=survived, 0=did not survive)

Buen día a todos, Alguien conoce si existe la manera de determinar cuellos de botella pasados o actuales en poblaciones naturales remanentes con información genética (microsatélites) en R.

Hi, i''m running a two dom0 nodes cluster for HA, and xen domUs running on top, currently it handles 5 domUs. The issue is that there''s a domU that can only run on one node, it''s not possible to start it on the other one. I get a ''b'' status and can''t access the console. Other domUs can start in either node and I can access their console without

Hi, I wanted an opinion on the most xen-compatible linux distro. Im embarking on a 4 month project with xen which involves the following objectives: 1.>Creating a tool with GUI that allows a)starting,stopping restarting domUs b)maintaining a status log of domUs c)migration of dom Us d)

can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

Hi, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM

Hello Puppet Users ! We encounter a problem with the dashboard on this URI : /reports/changed The /reports works fine with ~130000 reports (up to 3 months and auto-cleaning with rake reports:prune job) I make a reports:prune:orphaned, juste in case, but without any success. The most recent change on the server was the puppetmaster upgrade from 3.0.2 to 3.1.0. Here is the dashboard error log
