I am using rmagick to convert files stored as a tiff to either pdf or jpg for display to the user. A snippet of test code from the controller follows. It works OK. ( it does need a sanitizer ) require RMagick def pdf @sdoc = Sdoc.find(params[:id]) @fname = ''/var/www/images/'' + @sdoc.fname @nf = Magick::ImageList.new(@fname)

Is there a way for me to do: OrderItem.find(:all, :include => [:user, :product => [:supplier]] So I don''t have a supplier_id on my order_item, but have it on my product, which is part of order_item. Joerg -- Posted via http://www.ruby-forum.com/.

Hi all, I am NOT a person with English as my mother language and I haven''t been programming long enough to be natural in these kind of things. And if that isn''t bad enough, I am a newbie on Rails too... So please enligthen. I am trying to build a simple tool for my shop. I have many products that I sell in my shop and of course I have many suppliers for the products. Thus

I'm trying to plot a scatterplot of two variables using pch to plot different characters based on a third factor. Here is my example > data("ToothGrowth") > attach(ToothGrowth) > levels(supp) [1] "OJ" "VC" > plot(len ~ dose,pch=as.numeric(supp)) > legend(locator(1),pch=as.numeric(supp),legend=levels(supp)) The command as.numeric(supp) returns 2 2

Hi all, I I need to manipulate the x axis in a stripchart. I will use one of the data sets included in R to explain what I need to do. attach(ToothGrowth) stripchart(len[supp=='VC']~dose[supp=='VC'], vertical=TRUE, group.names=c('A','A','A')) stripchart(len[supp=='OJ']~dose[supp=='OJ'], add=TRUE, vertical=TRUE, at=c(1:3)+.1,

I''m getting an exception when I query a large index (4GB, ~700K docs) on a particular field. For example: supplier_id:77490 IO Error occured at <except.c>:93 in xraise (IOError) Error occured in fs_store.c:293 - fsi_seek_i seeking pos -1515676213: <Invalid argument> Anecdotally it seems to happen for supplier_ids > 76900. Here is the field info for that

Is it possible to add standard error bars to the means on interaction plots? Thanks Murray -- Murray Pung Statistician, Datapharm Australia Pty Ltd 0404 273 283 [[alternative HTML version deleted]]

Thank you for your guys reply for my previous question. But I got one more question about the boxplot. With the code in the R-help: boxplot(len ~ dose, data = ToothGrowth, boxwex = 0.25, at = 1:3 - 0.2, subset = supp == "VC", col = "yellow", main = "Guinea Pigs' Tooth Growth", xlab = "Vitamin C dose mg", ylab =

Dear List, ? I am creating a boxplot with two subsets, very similar to the example by Roger Bivand at ?boxplot (reproduced below).? I am trying to change the labels on the x-axis to have one number to cover both subsets.? I can do this in other plots by using axis=FALSE followed by a separate axis() command.? I have also tried variations in the names= argument but can't get it to work.?

Dear list, How can I add the mean and standard deviation to each of the boxplots using the example provided in the boxplot function? boxplot(len ~ dose, data = ToothGrowth, boxwex = 0.25, at = 1:3 - 0.2, subset = supp == "VC", col = "yellow", main = "Guinea Pigs' Tooth Growth", xlab = "Vitamin C dose mg",

Looks like Rails 3 currently depends on RDoc 2.2.0 exactly, even though the latest version is 2.5.x.

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)

Hi, Apologies for reposting this for those who read this via ruby-forum, but it didn''t make it to the list before, and the list seems more active... I''m using ferret (via acts_as_ferret) in a somewhat unorthodox manner and am having a strange wildcard problem. Before anyone wonders why we''re doing things this way, the answer is basically that it lets us

Hallo all, I was trying to Build LLVM with the cmake option LLVM_ENABLE_MODULES just out of curiosity. I used the RELEASE_400/final tag. It didn't work as I almost expected. So I'm wondering if the modulemaps aren't maintained anymore? If they aren't maintained anymore, why aren't they removed and that cmake option also removed?
