Dear all, I am stuck at applying loop function for creating separated plots. I have coding like below: dataset.table <- table(data.frame(var1=c(1,2,3,1,2,3,1),colour=c("a","b","c","c","a","b","b") )) kk = function(f) { ls=as.character(f) pie(dataset.table[ls,],main=ls)

Dear all, I have a task to find the first all zero row of a matrix X ( nothing known about X). I need to write a function which returns either the row index of the first all-zero row, or NA if there are no all-zero rows. and I also need to locate all rows which are non-zero (should be a vector of row indexes). Can somebody give me some hints on this? Thanks a lot. Rene. [[alternative HTML

Dear All, I have created a barchart, but the legend created by auto.key does not match the actual graph. Can someone give me some hint here? For example, my coding are: Library(lattice) dataset.table <- table(data.frame(id=c("a","b","c","a","c","b","a"),colour=c("blue","green","

Dear all, I have a question about loading the data to barchart plot. I know this could be a very easy question, but I just can not get my head around. What I need to do is to create a trellis plots barchart style (horizontal bar), with levels of one variable (ie. variable “colour” in my example) as ylab and frequency as xlab on each trellis plot. The trellis plots is separated based on

Dear All, Can someone please guide me how to get the certain part from a long html language? e.g. "<td><a href='2005-01.html'>2005-01</a></td><td><a href='2006-01.html'>2006-01</a></td><td><a href='2007-01.html'>2007-01</a></td><td><a

Dear all, Have you experienced problem of using numerical.summary() function? I used to be able to run this function in R, but not any more. Now I try to use this function, it gives me error like this: Error: could not find function "numerical.summary" I used to be able to run this function under library(s20x). Can someone please guide me on this ? Thanks. Rene

Dear All, In R, is there a way (or a function) I can quickly check whether all the NA values in one new created numerical variable happened are because of &nbsp; or something else in the original dataset? And how can we easily group these NAs separately based on different reason (e.g. some NA are because of &nbsp; , some are because of there are extra text inside, etc). Thanks

Dear all, I have a question about how to load data or (entering data )to each cell of a rectangle created by rect . e.g. I have a matrix rbind(1:2,1:2) I have created a 2x2 rectangle by using: a<-0:1/10 b<-0:1/10 kk<-expand.grid(a,b) plot.new() rect(kk[, 1], kk[, 2], kk[, 1] + .1,kk[, 2] + .1) so how do we put the value of rbind(1:2,1:2) into the relevant

Dear All, I need to write an R function which computes values of Probabilities for the (standard) normal distribution, ¦µ(z) for z > 0 by summing this power series. (We should accumulate terms until the sum doesn't change). I also need to make the function work for vector of values z. The initial fomular is ¦µ(z) = ( 1/ sqrt(2¦Ð) )* ¡Ò e^(-t^2/2)dt (¡Ò is from -¡Þ, z)
