Change Rcode for a meta-analysis(netmeta) to use a random effects model instead of a mixed effects model
Hello, I am writing a meta-analysis on the complication and reoperation rates after 5 treatment modalities of a distal radius fracture. I have a code to compare the complication and reoperation rates. Currently it is using a mixed effects model. Is it possible to change the code so a random effects model is used? Thank you very much, Jay R code library(meta) library(readxl) All <-

Model studies in one analysis using treatment as a five level moderator in a meta-regression
Hello, I am medical student, writing a meta-analysis on complication and reoperation rates after the five most common treatments of distal radius fractures. I have been busy with the statistics for months by my self, but find it quite hard since our classes were very basic. Now I want to compare the treatment modalities to see if there are significant differences. Using R I was able to

Dear Vito, Thank you for your reply. I tried to contact the statistics departement numerous times, but did not receive any reply. That is why I started to look on the internet for help.

Two questions, first about contingency tables, and second about table () and data.frame (), from a visually impaired user.
Hi all, I want to make a contingency table in R. I want to tabulate two variables, one as the independent and second as the dependent variable. The IV has two categories, namely, birth complications, and no birth complications. The frequency of birth complication category is fifty, and the frequency of no birth complication category is 34. The categories and frequencies of DV follows.

how to use quadrature to integrate some complicated functions
Hello to all, I am having trouble with intregrating a complicated uni-dimensional function of the following form Phi(x-a_1)*Phi(x-a_2)*...*Phi(x-a_{n-1})*phi(x-a_n). Here n is about 5000, Phi is the cumulative distribution function of standard normal, phi is the density function of standard normal, and x ranges over (-infty,infty). My idea is to to use quadra...

setting up complicated ANOVA in R
Hello. I am about to do a rather complicated analysis and am not sure how to do it. The experiment has a split-plot design and also repeated measures. Both of these complications require one to define an error term and it seems that one cannot specify two such terms. The split-plot command is: aov(y~covariates +A*B+Error(C), data=) whe...

ControlPlayback can not replay complicated file names
If not sure if I am looking at a bug or expected behaviour as I do not see anything in the documentation. ControlPlayback can not replay complicated file names For example it can replay 1005 but it can not replay 1005-2014-04-08_23:58:17 Playback can replay 1005-2014-04-08_23:58:17 I suspect this relates to how the variables are parsed and parameters set. Does anyone have any further information to suggest what the limitations are around...

Comparing pooled proportions(complication and reoperation rates) of different treatment modalities
Dear sir/madame, I am currently writing a meta-analysis on the complication and reoperation rates of 5 different treatment modalities after a distal radius fracture. I was able to pool the rates of the 5 different rates using R. Now I have to compare the pooled rates of the 4 treatment modalities with the golden standard separately. I though the chi squared test would be the best method. How do

How can I read the following complicated table
Hello, I have a table (in a txt file) which look like this: Monday 12 78 89 Tuesday 34 44 67 Wednesday 78 98 2 Thursday 34 55 4 Then the table repeats Monday , Tuesday, ... followed by several numbers My goal is to read values after the table. My problem is a little more complicated, but I just present a simpler case for ease of illustration. Is there any way to ask R to "read several number after you see the word 'Monday' and store somewhere", and read several number after you see the word 'Tuesday' and store somewhere"? Thanks, miao [[alt...

[LLVMdev] APFloat storage complications
APFloat is derived from C code using fixed width storage for the matntissa. When converting to C++ I changed it to variable- width storage for space efficiency and generality reasons. Unfortunately this leads to a complication during float->float conversions that I missed that isn't present when using fixed width storage. Dale - I think this solves the issue correctly whilst preserving

[LLVMdev] [RFC] Raise minimum required CMake version to 3.0
...pdating the bot is not an option. It indeed is an option, but requires cmake to be manually downloaded and installed instead of using the available packages. This is OK for one bot, but it will add complications for everybody who uses debian and wants to install LLVM. It also will make it more complicated to move to a fully cmake based build as all such debian based buildbots would require a manual installation of cmake (I have 12 more of these). Before doing so I wanted to understand if it is indeed intended to require debian-stable users to *manually* install and manage cmake or if there is n...

Accessing a c-level complicated structure from R
...ed list for what I'm to ask: soory if I'm wrong. I am a c newbie but nevertheless I am trying to 'couple' an extern c software with R. The compiled library is actually a stand-alone c program, which uses text file for input and output. It uses *lots* of differents and (to me) rather complicated and nested "struct"s to represent data for intern calculation. I want to make this program a -shared lib to use with R. I have (among many others) the following question: can I access from R a c-level defined struct, as input/output of my .C called function? If yes... how? Any clue, manu...
