search for: causation

...you like, but no one else seems to > have this > problem. Including me -- I've been subscribed to the Samba list for years and I don't get unmanagable numbers of viruses. I've also seen bursts of virus traffic for no apparent reason. It could be a coincidence. Correlation != causation. There's also always the question of what your ISP is doing. My ameritech.net account gets vast quantities of spam, and started getting it before I even used it! I can only assume Ameritech is selling their email list.

Could be. However, I think editing comments in a .R file is a bit harder than editing text in a .Rd file, so I think the format discourages editing.

I have installed Paradox Corel and the first time all ok. After stopping computer Paradox is blocked Unhandled page fault on read access to 0x00000000 at address 0x54da69 (thread 0009) and then start debugging. I have read thet this problem is causated by policy of restriction of access in Ubuntu and it is semple change this, but I dont know the command.

In so far no changes are needed. But besides of all, their are to many misprints in the first Edition. If you should be dissatisfied with the misprints, plea...

In response to Duncan regarding the use of roxygen2 from the point of view of a current user, I believe the issue he brings up is one of correlation rather than causation. Writing my first piece of R documentation was made much easier by using roxygen2, and it shallowed the learning curve substantially. What Duncan may be observing is a general tendency of roxygen2 users to write overly concise documentation. However, I believe this to be caused by an omitted vari...

Mehmet, That is a loaded topic, not unlikely other topics preoccupying us these days. There is package.skeleton() in base R as you already mentioned. It drove me bonkers that it creates packages which then fail R CMD check, so I wrote a wrapper package (pkgKitten) with another helper function (kitten()) which calls the base R helper and then cleans up it---but otherwise remains faithful to it.

Hi! I'm trying to implement an outlier test once/row in a large dataframe. Ideally, I'd do this then add the Pvalue results and the number flagged as an outlier as two new separate columns to the dataframe. Grubbs outlier test requires a vector and I'm confused how to make each row of my dataframe a vector, followed by doing a Grubbs test for each row containing the vector of numbers

Hello everybody, I need to know which samples (S1-S6) contain a value that is bigger than the median + five standard deviations of the column he is in. This is just an example. Command should be applied to a data frame wich is a lot bigger (over 100 columns). Any solutions? Thank you very much for your help!!! > s Samples A B C E 1 S1 1 2 3 7 2

Hi I have a dataframe which has 3 columns of numeric data A,B,C each of which has been obtained independent of the other. We are trying to find out, which of A or B cause C i.e. We are hypothesising that C is the effect and either A or B, not both is the cause. i.e. A causes C and this cause-effect relationship explains B. The data for A contains more noise than that for B. We are working with

...models are useful. Don't fall in love with a model. It is a capital mistake to theorize before one has data. Sherlock Homes in "Scandal in Bohemia" (Conan Doyle) It is not unusual for a well-designed experiment to analyze itself. Correlation may have nothing to do with causation: beware the lurking variables(s)! The idea of a process in a perfect state of control contravenes the second law of thermodynamics: thus a state of control is an unrealizable and must be regarded as a purely theoretical concept. The design of experiments was invented by R.A. Fisher to m...

Dear All, I'am looking for examples showing that correlation does not imply causality, the targeted audience consists of undergraduate students (their first year at the university but in the BioMathStat track). All practicals are under R. I was able to extract this from R datasets: ### begin data(sunspots) data(lynx) spots <- window(sunspots, freq = 1, start = 1880, end = 1900) lnx <-

Thunderbird (2.0) is all of a sudden checking mail server capabilities and keep posting a popup saying: "Mail Server imap.bard.edu is not an IMAP4 mail server". To the best of my knowledge, neither Tbird nor DC have been updated, though the DC imap host was rebooted today 3 hours ago. Any info on what this is about? DC is currently serving out of a special port and in evaluation

This is my first post here, and i hope it is ok that i posted in this thread. I have been doing a bit of reading on the solaris platforms, and seem to be inclined to try out the open solaris os or solaris 10. My only worry is that my lack of knowledge with the command line may make this difficult regarding trouble shooting. It seems fairly straighforward creating zpools etc, but maybe nexenta is

I have been following the discussions on 'Reasons not to answer very basic questions in a straightforward way' with interest as someone who is also new to R and has had similar experiences. As such it with sadness that I note that most seem to agree with the present approach to the responses to basic questions. I must thank those respondants to my own questions who have been helpful, but
