search for: dimesions

I don't find rbind, cbind or other bind that bind in other dimesions for multidimension array while keeping the result of the same dimension. For example, say, dim(x)=c(2,3,4), dim(y)=c(3,3,4). I want to have the result z, where dim(z)=c(2+3,3,4), when I bind x and y in the first dimenion. The bind can also be in the 2nd and 3rd dimesion. Could somebody let me kno...

Dear R people. I´m facing a big problem. I need to create a matrix with 10.000 columns and 750.000 rows. matrix<- as.data.frame(matrix(data=0L, nrow=750000, ncol=10000) as you can see, the data frame has huge dimesions. I was able to find out about thr "L" in data, this way I´m telling that my data is "integer" class. By doing this object.size(matrix) tells me that this is half of the matrix when I don´t define as integer (L) The data that I´ll be filling with my matrix will be 0 and 1, nothin...

Hello I have 2 datasets say Data1 and Data2 both are of different dimesions. Data1: 120 rows and 6 columns (Varname, Vartype, Labels, Description, ....) The column Varname has 120 rows which has variable names such id, age, gender,.....so on Data2: 12528 rows and 120 columns The column names in this case are V1, V2, ......... V120 (which are default names in R when we s...

Hi, I need to estimate the density at the mean of a sample of a few thousands data points with a dimesion up to 5. The data is uni-modal and regularly shaped. I couldn't find any kernel density package for R which supports more than 3 dimensions. Have I overlooked a package or does somebody have code for this purpose? Any other advice? Regards, Stephan

I would like to have some function for getting an overview of the variables in a worksheet. Class, dimesions, length, number of missing values,... Guess it wouldn't be that hard to set up such a function, but I guess there are others who have made it already. Or is it already a standard feature in the base package? Any suggestions? Robert

...ly the same time of computation. I was astonished since I expected at least sapply to outperfomr the for-loop. Do you have me another solution, which is faster? many thanks here is the code ## ------------------------------------------------------ t.length <- 5 d.dim <- c(t.length,7,8,9) # dimesions: time, x, y, z Y <- array( rep(1:t.length, prod(d.dim)) + rnorm(prod(d.dim), 0, 0.1), d.dim) X <- c(1,3,2,4,5) ## -------- performance tests ## using for loop date() z <- rep(0, prod(d.dim[2:4])) l <- 0 for (i in 1:dim(Y)[4]) for (j in 1:dim(Y)[3]) for (k in 1:dim(Y)[2]) { l...

...bugs on the vorbisfile API/library Hone the LPC approximation routines a bit more. Get the command line player functional (Mike Whitson is also planning to put some time in here). Verify that I understand the LSP probability distributions by making lots of 12-32 dimensional graphs (well, OK, 3 dimesions at a time :-) Code the codebook abstraction learning interface, spec the encode/decode interface. Most of the above doesn't really have an impact on applications coding, it's just libvorbis internal. The external API is just about complete (only one change in the last month, adding a sec...

Hello, i want to create a multidimensional Array or Hash with group_by ''created_at''. 3 dimensions needed: myArray[week][day][data] currently i only created it with 2 dimesions: #model def self.group_per_day all.group_by{|t| t.created_at.strftime("%d. %B, %Y")}.sort #"%U" for Weeks end #controller @pdf_activities = Activity.group_per_day #view -@pdf_activities.each do |day| =day[0] -day[1].each do |activity| =activity.activity thanks --...

Hello people, Is there some simple way of spinning and/or flipping arrays in R? Here's what I mean. Suppose that foo is a 2x3x4 array with the following contents: (I know this is different than typing 'foo' at and R prompt, but I'm so used to row major order from using APL, I have a hard time with R's output) > foo[1,,] [,1] [,2] [,3] [,4] [1,] 1 2 3 4

I sent a little mail some time ago asking if there was going to be an ogg pic-format, and you replied that PNG, MNG and JNG is good enough (sorry for this late answer btw).. But, consider this: The ogg video-format (tarkin ? where do you get these names from anyway ? :) ) needs a way to compress its frames. Are you going to use MNG for that ? :) .. If you had an ogg pic format, that format could
