similar to: TRUE/FALSE

I have data X and Y, and I want to predict what the very next point would be based off the model. This is what I have: >model=lm(x~y) I think I want to use the predict function, but I'm not exactly sure what to do.

I need to write an if/then statement saying something along the lines of: if (VALUE is in list) {... How do I write that in R's language.

Hi to all, maybe the last question was not clear enough. I did not found any hints how to decide whether it should use lower.tail or not. As it is an extra R-feature ( written in http://finzi.psych.upenn.edu/R/Rhelp02a/archive/66250.html ) I do not find anything about it in any statistical books of me. Regards Carmen

What i have is a for loop to name files. I want it to skip over the file if it doesn't exist. Is there a way to do that? s=seq(from = chron("03/15/2012"), to = chron("06/15/2012")) day=format(as.Date(s), "%Y%m%d") for (k in 1:length(day)){ B1=read.csv(paste("S:/file_", day[k], ".csv", sep="")) Date=strptime(B1[,1],

Hi, Why does the upper left panel (in the plot below) not have a gray background? Cheers, Marius require(grid) require(gridBase) pdf(file="Rplot.pdf", width=8, height=8, onefile=FALSE) ## set up the grid layout gl <- grid.layout(5, 5, widths=unit(c(1.8, 8, 0.8, 8, 0.8), "cm"), heights=unit(c(0.8, 8, 0.8, 8, 1.5), "cm")) if(FALSE) grid.show.layout(gl)

Dear all, I'm trying to get a series of lattice levelplots to appear in viewports in a particular way but struggling to exert fine control over their appearence. There are two conditions: (a) I only want the levelplot to appear (I don't want axes, colour key, etc) in the viewport and (b) I want the levelplot to expand to the maximum allowable space in the viewport while observing

Dear all; Searching the R site for answers to my problem, but found none. Here is the run and error: > bwplot(dev ~ Dbhcl | Period, data = DbhValid2, font = 2, + main=list(" "), axis.font =2, + ylab = list(label = "Residual (cm)", font = 2), + xlab = list(label = "Dbh class (cm)", font = 2), + par.strip.text=list(cex=0.8, font=2), + panel=function(x,

Hello, I created several plot with ggplot2 dev mode. Now I want to combine the plots in a grid e.g. 2x2 with a fixed size of the output. What I am doing at the moment is: grid.newpage() pushViewport(viewport(layout = grid.layout(nrow=2, ncol=2, widths = unit(c(7.5,6.5), "cm"), heights = unit(rep(5, 2), "cm")))) print(plot1, vp = viewport(layout.pos.row = 1,

I tried to use LME (on a fairly large dataset, so I am not including it), and I got this error message: Error in lme.formula(formula(paste(c(toString(TargetName), "as.factor(nodeInd)"), : nlminb problem, convergence error code = 1 message = false convergence (8) Is there any way to get more information or to get the potentially wrong estimates from LME?

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

Dear grid expeRts, I would like to create a layout with grid that looks like the following, but with cells (1,1), (1,4), (4,1), and (4,4) removed and cells (2,1) and (3,1) (and (4,2) and (4,3)) combined to one cell (so that contents can easily be centered. How can this be achieved? require(grid) gl <- grid.layout(4, 4, widths=unit(c(1, 3, 3, 1), "cm"),

Can a temporary message in Asterisk voicemail be de-activated so that the "regular" unavailable and busy messages are played. I have several users who are stuck with the temporary message. Thanks Mark

I apply isoMDS to my data, but the result turns out to be bad as the stress value stays around 31! Yeah, 31 ,not 3.1... I don't know if I ignore something before recall isoMDS. My code as follow: m <- read.table("e:/tsdata.txt",header=T,sep=",") article_number <- ts(m, start = 2004,end=2008, frequency = 1 ,names=colnames(m))

Hi, I encounter a situation where I have a list whose element is a column matrix. Says, $'1' [,1] 1 2 3 $'2' [,1] 4 5 6 Is there fast way to collapse the list into a matrix like a cbind operation in this case? Meaning, the result should be a matrix that looks like: [,1] [,2] [1,] 1 4 [2,] 2 5 [3,] 3 6 I can loop through all elements and do

Does anyone have code that will methodically process R sourcecode, turning T's into TRUE and F's into FALSE? I got bored doing this by hand, after the first 30-odd functions-- there are hundreds left to do. I don't want to simply deparse everything, because that would destroy my beautiful formatting. The reason it's not trivial, is that comment lines, quotes, and split lines need

Hi, not sure if I'm posting in the right place but couldn't find a SWAT forum. I've just changed my PC but the new one has exactly the same settings (IP, computername, login, password) as the old one, however I am getting an error when I try to access any of my Samba servers from Firefox (2.0.0.3) :- " 400 Server ErrorSamba is configured to deny access from this client Check

Checking the databases against each other throws up pages and pages of errors. The two are completely out of sync now. What I have seen is that for no apparent reason, one of the servers suddenly decided it would sync with the Windows server, which appears to have updated the schema. Yesterday when I compared the databases on the two linux servers they only had a couple of errors, today, many

Hi everyone, I need to recode multiple columns in a dataframe into a single column in a variety of different ways. Often the values will be TRUE/FALSE and I want a list of the columns that are true as in the Result column below: P1 P2 P3 P4 Result 1 0 0 1 1 P3,P4 2 0 1 1 1 P2,P3,P4 3 1 0 0 0 P1 4 0 0 0 0 NA 5 1 1 1
