Hello, the code below gives me the picture I need - but there is on small thing I can't figure out. The plot has very small tick mark labels for both axes. I don't mean the axis labels - they are both good, but what is shown near the tick marks. Please help me figure out what parameter I should add to make those larger. I tried sticking cex.lab=1.3 in different places but it didn't

Hello! I apologize - I never used lattice before, so my question is probably very basic - but I just can't find the answer in the archive nor in the documentation: I have a named numeric vector p of 6 numbers (of the type 6 numbers with people's names to whom those numbers belong). I want a simple bar chart. I am doing: library(lattice) trellis.par.set(fontsize=list(text=12)) #

A question about the layout of structs: I decided to make my vtables out of structs rather than arrays. In other words, instead of being a table of opaque pointers, I decided to individually declare each entry with the correct type for that method. I figure that the various optimizers could do a better job if I preserve the type info. OK, so we come to the issue of inheritance: Suppose I have

Hello, I'm using ROCR to plot ROC Curves and I want to automate the saving of plots into PNG files using a custom function. My data frames are named like test1, test2, test3. Each data frame has three variables: method1, method2, goldstandard. Right now, for each plot I have to run: png('test1_method1.png') plot(performance(prediction(test1$method1, test1$goldstandard),

Hello Kalyan, There is one more thing you should know: Clang has maximum optimization turned on by default. You need to specify -O0 to turn it off if you want to see what opt does without clang running all of the optimizations first. --Sam ----- Original Message ---- > From: Duncan Sands <baldrick at free.fr> > To: llvmdev at cs.uiuc.edu > Sent: Sat, April 17, 2010 2:00:00 AM

Full_Name: Jens Oehlschl?gel Version: 2.5.1 OS: Windows Submission from: (NULL) (62.159.183.42) Even when specifying the full path, the output of fc is not sent to R (neither shown nor returned).

JavaScript doesn''t (yet) have a notion of classes. Prototype.js just adds a suitable convention for implementing them. It provides a way to create a new class by extending a base class using Object.extend, but it doesn''t handle method inheritance. There are ways of doing implementing this through traversing the chain of prototypes, but I''m not sure they are

Dear all, I want to compare the efficiency of 2 methods in extracting proteins from algal samples. I collected 6 independant algal samples and I extracted 3 by the method 1 and 3 others by the method 2. So I have 2 groups of 3 samples, that are not paired. I would like to know if the results obtained by these 2 methods are significantly different, I hope method 2 to be more efficient than method

Hello! I wrote a function that returns a data frame. Nowhere in the function do I say print(my.data.frame), but when I run the function - the data frame is printed on the console. Is there any way to suppress it? Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

Hello, I am frastruated with this graph, just cannot get what I need. Thank you for any suggestions or help. I really appreciate it. I wrote the following code, but there are 3 problems 1, the red line is added on the graph but without any marker on the y-axis. I want to display the number '.1361' on the y-axis. So people can easily tell 'method 2' gets a constant estimate, which

Hi Kalyan, > opt -strip-dead-prototypes -f <filename.bc> filename2.bc you have to specify the list of passes to run. -strip-dead-prototypes only removes unused declarations. If there are none, it will do nothing. Try: opt -std-compile-opts -f <filename.bc> filename2.bc Ciao, Duncan.

Hello! s<-"start"; e<-"end" middle<-as.character(c(1,2,3)) I would like to get the following result: "start 123 end" or "start 1 2 3 end" or "start 1,2,3 end" How can I avoide this (undesired) result: paste(s,middle,e,sep=" ") Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

Hello! I am wondering if it's possible to run - in sequence - code that is stored in several R scripts. For example: Script in the file "code1.r" contains the code: a = 3; b = 5; c = a + b Script in the file "code2.r" contains the code: d = 10; e = d - c Script in the file "code3.r" contains the code: result=e/a I understand that I could write those 3 scripts

Dear R-ers! I have x as a variable in a data frame x. x<-data.frame(x=c("aa.bb","cc.dd.ee")) x$x<-as.character(x$x) x I am sorry for such a simple question - but how can I replace all periods in x$x with spaces? sub('.', ' ', x$x) - removes all letters to the left of each period... Thanks a lot for your advice! -- Dimitri Liakhovitski Ninah.com

Hello, I am trying to understand the opt tool. I wrote a program and created the .bc file using clang. And I used this .bc file to generate another .bc file using the opt tool. I dis-assembled this bitcode file and compared the output with previous unoptimized bitcode file. It was the same. I am not sure how to check the difference. Can anyone tell me if this is how we check the optimized output

I am not sure if this question has been asked before - but is there a procedure in R (in lm or glm?) that is equivalent to ENTER and REMOVE regression commands in SPSS? Thanks a lot! -- Dimitri Liakhovitski Ninah.com Dimitri.Liakhovitski at ninah.com

Dear R'rs, is there a function that checks if a given vector contains a certain value. E.g., x<-c(1,2,3,4). How can I get a TRUE or FALSE for whether x contains a 2? -- Dimitri Liakhovitski Ninah.com Dimitri.Liakhovitski at ninah.com

Dear R-ers, I have a large data frame (several thousands of rows and about 2.5 thousand columns). One variable ("group") is a grouping variable with over 30 levels. And I have a lot of NAs. For each variable, I need to divide each value by variable mean - by subgroup. I have the code but it's way too slow - takes me about 1.5 hours. Below is a data example and my code that is too

Thanks duncan and samuel. I guess the optimization about striping dead prototypes was not working because of "no dead prototypes" to strip. The -std-compile-opts option works. I can see a change. And @samuel, I tried the clang's -o0 optimization level compiling, but I could not find any difference with or without that switch in the bitcode file generated. I used this command: clang

I know that I can use as.yearmon in the package "zoo" to find the year and the month of a date. I can use as. yearqtr to find the year and the quarter. But how can one find just the year of a date? Thanks a lot! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com
