Hello, Can anyone help me out with this problem? After performing logistic regressions and testing the significance with likelihood ratios, I have plotted the results using "termplot". I am wondering, how to get the names of my variables to appear on the x-axis rather than ascending numbers? I have used: termplot(fm, se=T, axes=FALSE, col.se="black") axis(1, 1:4,

Hello, I want to perform a latent class analysis using poLCA package. My formula is: substances <- cbind(subs1, subs2, subs3, subs4, subs5, subs6) ~ gender+age+education+income+occupation+urban+dbehavior+incarceration+treatment+depression+alcriteria I want to include sample weights in the model, I have read that poLCA does not take into account weights, but when I introduce them, it seems

Dear Rxperts, I am aware of Sweave that generates reports into a pdf, but do know of any tools to generate to export to a MS Word document... Is there a way to use R to generate and export report/publication quality tables and figures and export them to MS word (for reporting purposes)?

Dear Rxperts! My colleagues used SAS PROC COPY to generate the xpt files that could be read by the available "xpt" file reading packages in R. However, I am unable to use the R packages for reading SAS transport files generated through SAS PROC CPORT. I have tried SASxport, Hmisc, and foreign. Any ideas/suggestions are more than welcome! Thanks so much! Santosh [[alternative HTML

Dear Rxperts, Below is a small sample of values (cut short due to space considerations while posting).. I was wondering if it is possible to construct boundaries (or intervals) based on the distribution of points. Is it anything similar to boundary detection of distributions? x1 <-

Dear Rxperts, q <- data.frame(p=rep(c("A","B"),each=10,len=30), a=rep(c(1,2,3),each=10),id=seq(30), b=round(runif(30,10,20)), c=round(runif(30,40,70))) The operation below... tabular(((p=factor(p))*(a=factor(a))+1) ~ (N = 1) + (b + c)* (mean+sd),data=q) yields some rows of NAs and NaN as shown below b c p a N mean sd mean sd A 1 10

Dear Rxperts Below is a small vector of values of zeros and non-zeros... was wondering if there is an efficient way to get the block sizes of submatrices of a big matrix similar to the one shown below? diagonal elements can be zero too. Rows with only a diagonal element may be considered as a unit block size. c(1,0,0,0,0,0,0,0,0,0,0, 1,1,0,0,0,0,0,0,0,0,0, 0,0,1,0,0,0,0,0,0,0,0,

Dear Rxperts, is there way to identify intervals from continuous data (having some kind of a pattern) and then pick the value of most frequency? a1 <- round(rnorm(50,mean=0,0.1),2) a2 <- round(rnorm(50,mean=1,0.2),1) a3 <- round(rnorm(50,mean=5,1),0) a4 <- round(rnorm(50,mean=14,4),0) a5 <- round(rnorm(50,mean=30,8),0) b1 <- rbind(a1,a2,a3,a4,a5) hist(b1,brea=100) # shows

Dear Rxperts! A simple example where "write.csv" does not seem to accept user specified arguments.. Why? write.csv(t(1:10),"./te1.csv",quo=F,col.names=F) Warning message: In write.csv(t(1:10), "./te1.csv", quo = F, col.names = F) : attempt to set 'col.names' ignored However, write.table does fine..

Hey folks, Last release was a long, long time ago. Pierre & I got a lot of work on our respective jobs. Anyway, I spent some days to complete some work on Syslinux & HDT. My current git tree is now featuring an ACPI implementation that allow parsing the structures (dsdt, ecdt, facs, fadt, madt, rdsp ,rsdt, sbst, xsdt) This pre-release of HDT is so featuring this table detection + cpu
