Hi All, I'm fitting a Poisson regression. And I want to plot 95% Confidence Interval of Regression Estimates. After coming back to original scale (using following formula): exponential(estimate +/- 1.96*SE), at best I can get the output in the form of estimates, lower_limit, upper_limit values. As far I know forest() in metafor package needs input in the form of estimates and their

Hi All, I'm wondering if its possible to write degree in symbol. I would like y-label as "Temperature (degreeF)". where degree should be in symbols. Thanks in advance, #R Code library(lattice) data(barley) barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), ylab = "Temperature (degreeF)", scales = list(x =

Hi All, I want to produce a similar "Forest Plot" as it is on the following link, but my data would be having only two columns (one for "Estimate" and other for "Std. Dev"). Can anyone suggest some function() {Package} which can take such file as an input and give following forest plot:

Hi All, I'm dealing with binary response data for the first time, and I'm confused about what kind of graphics I could explore in order to pick relevant predictors and their relation with response variable. I have 8-10 continuous predictors and 4-5 categorical predictors. Can anyone suggest what kind of graphics I can explore to see how predictors behave w.r.t. response variable... Any

Hi All, Can someone help me reshape following data: Var1 Var2 Val A X 1 A Y 2 A Z 3 B X 4 B Y 5 B Z 6 to some kind of matrix/tabular format (preferably as a matrix), may be like Var1 X Y Z A 1 2 3 B 4 5 6 Any help would be greatly appreciated, Kim [[alternative HTML version deleted]]

Hi All, I'm a SAS user but I'm very much interested in learning R. I use ODS system in SAS to make nice frequency tables. Is it possible to export the output of table() [in TABULAR FORM]? So, that I can use those directly for publications? Thank you. # R Code: library(datasets) Orange summary(Orange) # outputing this, not as it is, but in table for. is it possible? ~Kim [[alternative

Hi All, I need a small help with following code: I'm trying to convert "dashed lines" to regular ones; and changing default "blue" border color to say "black"... but I'm doing it wrong and its not working. Can anyone help please. Thanks, Code: require(lattice) ex <- data.frame(x=1:10, y=rep(c("A","B"), 5)) bwplot(y~x, data=ex,

Hi All, I need a file which I can import to MS Word, I'm trying win.metafile(), but it does not seem to support multiple print commands at once (please see below). Is there an alternative to get plots file which can be used in powerpoint/word? # R code: # this does not work; but same thing works with pdf() library(lattice) win.metafile("test.wmf") p1 <- xyplot(decrease ~

Hello, I want to arrage the label according to my preference eg.. (va, vp, a, b, c) but don't know how to supress default ordering. Any suggestions? Please try the code below: n <- c("va", "vp", "a", "b", "c") p <- c(2, 2,1, 3,5) pm<- c(3,4,2,5,4) pn <- c(1,1,1,2,3) x<-data.frame(cbind(n,p,pm,pn)) library(ggplot2) qplot(x=n,

Dear All, I'm having trouble tweaking a forest plot made using the R meta-analysis package metafor. I did the analysis based upon the correlation coeff from studies and plotted the corresponding forest plot easily > q2<-rma(yi,vi,mods=cbind(grupo),data=qim) > q2 > forest (q2,transf=transf.ztor,digits=3, ... ,alim=c(0,1),refline=.5) > text(-1.55,42,"Esp?cie

Hello all, I am using forest.rma to plot a random effects model meta-analysis. I noticed that refline sets a vertical line indicating the null hypothesis. Is there a way to draw another vertical line, possibly dashed, centered on the summary estimate? Prof. Viechtbauer, if you happen to read this, I'd like to thank you for making an excellent package. I have been using the metafor package

Dear R-experts, The forest.rma() function from the metafor package creates nice forest plots for presenting the results of a meta-analysis. These plots can be annotated for e.g. giving names to the columns. E.g. as in the documentation of the package: data(dat.bcg) ### meta-analysis of the log relative risks using a random-effects model res <- rma(ai=tpos, bi=tneg, ci=cpos, di=cneg,

Hi All, Can anyone please help me with getting a single x and y-axis label while plotting muliple plots. Here is the code: par(mfcol=c(2,2)) plot(x <- sort(rnorm(7)), type = "s", main = "", ylab="", xlab="") plot(x <- sort(rnorm(27)), type = "s", main = "", ylab="", xlab="") plot(x <- sort(rnorm(47)), type =

Dear R community, I'm using the ,metafor'-package by Wolfgang Viechtbauer (Version: 0.5-5) to calculate random-effects meta-analyses using Correlations and Sample Sizes as the raw data. (By the way: Really a nice piece of work, Wolfgang! Thanks heaps.) I specified the "rma.uni' function so that it looks like this: MAergebnis<-rma.uni(ri=PosOutc, ni=N,

Hi All, I'm using glm() in R to perform Poisson regression, I'm wondering if its possible to get equivalent Type 1 / Type 3 Analysis (similar to one in PROC GENMOD). Thanks, Kim [[alternative HTML version deleted]]

Hello! I would like to draw a graph like the following: http://www.optics.rochester.edu/workgroups/cml/opt307/spr04/pavel/plot_small.jpg Aim is to plot confidence intervals of treatments for X(=response1) and Y(=response2) axis simultaneously to visualize aggreement of confidence interval for two responses. Can anyone please provide me some direction to start with? Thanks! -- Kim.

Hi All, Can anyone please suggest me from where should I start to learn about 'how to connect to access db' ?

Hi All, I need a small help plotting median lines on lattice boxplots. # Data a <- rep(c("A","B"), each=10) b <- rep(c("a","a+b","b","b+a"), each=5) c <- c(1,9,5,2,7,7,8,8,8,5,4,5,3,2,5,6,7,8,9,1) x <- data.frame(a, b, c) med.A <- median(subset(x$c, x$a=="A")) med.B <- median(subset(x$c, x$a=="B"))

I am using metafor to create forest plots. This code gives me the expected plot (setting x axis tick marks): forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, at=log(c(.05, .25, 1, 10)), slab=forest$SNP, atransf=exp) As does this (setting colors): forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, col=c(1,2,3), slab=forest$SNP, atransf=exp) But if I try to set both 'at' and

Hello, I experimented the Metafor and Meta packages in the scope of replacing Excel for meta-analysis. I performed the first working example provided in Michael Borenstein's book "Introduction to Meta-Analysis" with Excel, Metafor and Meta. The numbers given by my spreadsheet, which I validated from Borenstein's book, conrespond quite closely to those given by Meta, but
