Dear R help-list reader, I would like to generate a plot which compares to states in a patient treatment, before and after. for this reason I have generated a vector before<-c(1,30,23,40) and after<-c(20,10,20,60) the first element in "before" corresponds to the first element in "after". I would like and generate a dotplot with before and after as x-scale, the elements

Dear R users, according the help(log), the function log2(x) should give the natural logarithm of x. I expect in case of x=2 to to get 0.6931, however, R gives me 1 as a result. Similar, logb(2,2) gives 1 again. I'm wondering if I have missed something ?

Dear R-help reader, it would be great if someone knows what I'm doing wrong. I have (shorten) dataframe, which consists of a group identification and a number >ex UID REL 1 R1.B8.31 0.000 2 R1.B8.31 0.000 3 R1.B8.31 0.000 4 R1.B8.31 0.000 5 R1.B8.38 0.010 6 R1.B8.38 0.060 7 R1.B8.38 0.006 8 R1.B8.38 0.010 9 R1.B8.48 0.080 10 R1.B8.48 NA 11 R1.B8.48 0.006 I'm

Dear R users, I would appreciate for some advise how to generate a Tukey Mean-Difference Plot with the tmd function part of the lattice library. I have two test results (log transformed) which showing a correlation on a scatterplot. However the correlation line is parallel displaced depending on a clinical condition. I thought to a Tukey Mean Difference Plot would show me the difference

For me as a beginner a cookbook would be welcome. so many great code examples are posted into the help list, but finding these is quite difficult. I think it comes all down to the problem who is compiling / contributing and can judge what should go in. In this respect, Detlef Steuer (suggestion , might be a solution http://fawn.unibw-hamburg.de/cgi-bin/Rwiki.pl?RwikiHome. Frank >

Dear R help reader, I'm not an expert in R and are lerning a lot by reading the help digest, which is sometimes difficult because the huge amount of data posted. I have posted some questions before, and are impressed how quick I got a solution for my problem. Sometimes with quite different suggestions. I was always wondering if my questions didn't come up before. On the other site,

I have two straightforward questions about linking in the man pages for R packages: First, is it possible to link from within parts of the documentation that are not the \seealso section? For example, I would like to have something like: \arguments{ \item{correlation}{an optional \code{corStruct} object describing the within-group correlation structure; the available classes are given in

Good Morning (or not), I am running three Samba AD DCs all at version 4.7.2 on Ubuntu 16.04.  All three have run flawlessly for over a year. Last night one of the DCs started failing Replication with both the other DCs so I decided to run samba-tool dbcheck . Resulting in several: ERROR: orphaned backlink attribute 'memberOf' in CN=Annamarie Foyles,CN=Users,DC=cy,DC=cybernetics,DC=com

Let's say I would like to look inside the function corBrownian in library (ape). When I type in the function name I get the following, which is not nearly the detail that goes into this function. I am wondering how to begin cracking this function open (and others) so I can learn more about it and perhaps code my own corClass one day. Thanks. > corBrownian function (value = 1, phy, form

I noticed that ?corClasses in package nlme does not list corSpatial among the standard classes. This might either be intentional because corSpatial is not "standard" , or it might be simply an oversight that needs correcting. ------------------------------------------ Robert W.

Hello, I could like to get the a book which is suitable for me to learn Samba and its application on Microsoft OS like Win NT and WIn 2K .Kindly recommend me and where can I purchase one ? Thanks. Rgds, yipcl

Hi, I have been using the function lme() of the package nlme to model grouped data that is auto-correlated in time and in space (the data was collected on different days via a moving monitor). I am aware that I can use the correlation classes corCAR1 and corExp (among other options) to model the temporal and spatial components of the auto-correlation. However, as far as I can tell, I can only

[Mod: The to address has been changed. The original message has been CC'ed to linux-security. This is mostly FYI only -- alex] Winfried, Good question. Since Linux-2.2.* has hit the streets, I'm guessing there may be wider interest in this sort of thing so I'm CC'ing my reply to linux-security. The capability stuff in the kernel provides a way to strip away all of the privilege

i''m very new to the rails scene and am seeing lines of code like attr_reader, attr_writer, attr_accessor, etc... and have no idea what they do. reading the section in the book i''m reading that explains the previous block of code says nothing about it really. -- Posted via http://www.ruby-forum.com/.

Hi, Is there any way to 'administer' Samba's WINS database? I'm attempting to get Samba to take over our NT servers' current functionality so that we can ditch them entirely. I've enabled WINS support and told our DHCP server to point at it. Is there any way of viewing it's database to see if it's working? Also, our XP boxes connect to a domain which is

Hi all, Im slowly moving forward, but there''s something a miss. I can save some relational records to tables, but only once. For an unknown reason, the primary key (id) of the child table is not automatically increased. (I can only perform one save, (the first records id field holds the value ''0'') and during the next save it says: Mysql::Error: Duplicate entry

Hi to all, In other statistical software, such as Eviews, it is possible to regress a model with the Least Squares method, assuming that the residuals follow an AR(q) process. For example the resulting regression is something like y = 1.2154 + 0.2215 x + 0.251 AR(1) How is it possible to do the same in R? Thank you very much in advance, Constantine Tsardounis http://www.costis.name

A couple of questions: How to be sure that gls allowes errors to be correlated and/or have unequal variances? (is this on auto or is there a switch?)

dear list, I am wondering if one can find examples and/or more detailed descriptions of modifications needed when going beyond standard corStruct classes (i.e. those already provided for use in lme/nlme)? When I looked at pages 238-239 of Pinheiro/Bates (2000): Mixed-effects models in S and S-plus, I found that I would need a bit more explicit guidance what to do for implementing a new

Ezra, * test harness in new generated merb apps with helpers for testing merb without starting a server. * pin down plugin arch Seems to me that these two tasks go together unless you want to have rspec built in Merb. Regarding the test harness, my understanding is that: - a developer should be able to easily write specs against a merb application. - a developer should not need to start a merb
