similar to: grouping followed by finding frequent patterns in R

Hello, I'm using the eclat function of the arules package (1.0-6) for the identification of frequent itemsets. I need the tidLists, but if I set in the function tidLists=TRUE R crashes (Windows XP Professional SP3, 32 bit, R version 2.12.1 (2010-12-16), reproducible on two different computers) with two different error messages or non at all. Minimum examples are: library(arules)

Dear Collegues, it seems like there is a problem with the image()-method in the package arules. Using an ordninary matrix works fine: image(matrix(rnorm(200), 10, 20), axes = FALSE, col=brewer.pal(9, "Blues") ) delivers an image with blue colors and no axes. Using an object of the class "associations" (arules package) does not work: image(items(ta.eclat), axes = FALSE,

Let's say I have a list called the_list consisting of three components: the_list$component_1 the_list$component_2 the_list$component_3 Now, I want to access it using a variable called comp. comp <- "component_1" I'm looking for some function that let's me do this: unknown_function(the_list, comp) Which should do the same thing as: the_list$component_1 Any ideas?

Hi all, I have some problems inserting data into a legacy table. the key field of this table is a field named CIN which is a varchar(15). when I try insert into this table using a form (generated by the scaffold generator) I get this Error : _____________________________________________________________________ undefined method `CIN_before_type_cast'' for #<Candidat:0x370d8c8> |

Hi all, With the newest patches to LLVM, there should be no reason for having "#include <iostream>" in any library source code file, except for lib/ Support/Streams.cpp. Please use the following instead: OLD NEW --- --- std::ostream llvm::OStream std::istream llvm::IStream std::cerr llvm::cerr std::cerr llvm::cout

Hi, Ive just installed Samba 2.0.4b. The server has minimal load, but when I copy files from a PC (NT4 Workstation) to the Samba server, partway though the transfer I get the following error message. "Cannot copy <filename>: Network Access is denied. Be sure you have the correct network permissions to perform this operation" In log.machine the following error's are

Hello, I use caldera 2.4 , and evrything goes well with samba. Login, shares, homes and neighborhood but the windows stations cannot change their samba password on the Linux serveur. It allways answers that the old password is wrong and it is no. anyway the password was recognise at the login... Their is no relation with passwd sync or passwd chat. Thank you for your help (and your work ! ).

Dear all, the help of par() claims that cin and cra are c(width, height) but it appears to be rather c(height, width) Best regards Jens Oehlschl?gel > plot.new() > strheight("W", unit="inches") [1] 0.1354167 > par("cin") [1] 0.1354167 0.1875000 > version _ platform i386-pc-mingw32 arch i386 os mingw32

Hi, I am trying to infer the dimension of an opened bitmap (png, jpeg, bitmap device...) from par() parmeters. From the help on par(), I found that: > dim <- c(400, 200) > png("foo.png", width=dim[1], height=dim[2]) > dim2 <- par("din") * par("cra") / par("cin") > dev.off() > dim2 [1] 399.9999 199.9999 I've tried the above on

Is there a way to create a 'bubble plot' in R? For example, if we define the following data frame containing the level of y observed for 5 patients at three time points: time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))

Suppose I have this C++ program: #include <iostream> int main (int argc, char** argv) { while (1) { char cmd[80]; std::cin.getline(cmd, 80); std::cout << "response to " << cmd << std::endl; } } compiled by: c++ -o junk junk.cpp and I have this bash script: #!/bin/bash ./junk <<EOF blah bleh \cC EOF echo "Something

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Hi, I'm developing a Windows backup application that needs to be able to create possibly hundreds of thousands of hard links on an SMB share. I'm running into a strange problem when that share happens to be on a Samba server. When the application tries to create the 10000th hard link, the win32 CreateHardLink() function returns error code 5 "Access is denied". The Samba log

The solution (provided in Microsoft's documentation) is to add: #include <cstdio> #include <io.h> #include <fcntl.h> and run: int result = _setmode( _fileno(stdin), _O_BINARY ); if( result == -1 ) { std::cerr<<"Cannot set input mode to binary."<<std::endl; return 1; } result = _setmode( _fileno(stdout), _O_BINARY ); if( result == -1 ) {

Hello, R People: How do I change the size of a graph, please? I tried par(cin=c(8.5,11)) and it said that Warning message: parameter "cin" can't be set in: par(args) > par(fin=c(8.5,11)) > plot(xa,ya) Error in plot.new() : Figure region too large Also, can I set for portrait or landscape, please? Thanks in advance! Erin M. Hodgess, Ph.D. Associate Professor Department

Hy all I use barplot to draw frequencies by dates. On the x axis it shows only 1 date for 2 bars, i've understand why, because R cant put so much date on the same axis, it will get out of the graph. that's why i tought about reducing the size of the font used to stamp the x axis. anyone knows the right way? i've tryed par(cin) and barplot(cin=3) but it says i cannot do it at this

Hi, Does R have some way to function as the cin object in C++ like I generate a integer variable x in R, and I want the user to input the value x, like in C++ cin>>x I have been using R as a statistics graduate students for 2 years but never know any function similar like this. Any suggestion will be highly appreciated. Zhou [[alternative HTML version deleted]]
