As I want to generate code for the varaible declaration, at first, I thought AllocInstruction()could implement this. However, the name "alloc" seems to allocate memory from heap memory.and the local variable in function should stay at stack memory. In which way did llvm allocate memeory to AllocInstruction() ? Would the memory a...

Hello all I am a very new R user I am used to using STATA My problem: I want to build a Cox model and validate this. I have a large number of clinical relevant factors and feel the need to reduce these. Meanwhile I have some clinical variables I deem sufficiently important to force into the model regardless of AIC or p value. This is my present log over commands

Dear prof. Harrell, I'm not able to use the force option with fastbw, here an example of the error I've got (dataset stagec rpart package): > fitstc <- cph(Surv(stagec$pgtime,stagec$pgstat) ~ age + eet + g2 + grade + gleason + ploidy, data=stagec) > fbwstc <- fastbw(fitstc,rule="aic",type="individual") > fbwstc Deleted Chi-Sq d.f. P Residual d.f.

Greetings guRus -- If a variable, e.g., 'varname', is a character string, e.g. varname <- "datavector", and I want to apply a function, such as table(), to datavector, what syntax or method will do so using only the variable varname? This seems similar to indirect addressing, but I have not seen a method for it in the R manuals. Is there a general name for such indirect

I would like to produce a bar plot with varying-width bars. Here is an example to illustrate: ww <- c(417,153,0.0216,0.0065,556,256,0.0162,0.0117, + 726,379,0.0358,0.0501,786,502,0.0496,0.0837, + 892,591,0.0785,0.0795) yy<-t(t(array(ww,c(2,10)))) barplot(yy[,2*1:5],las=1,space=c(.1,.5),beside=T) produces a barplot of 5 pairs of bars that are of equal width

Hi we wanted to access a class varaible from outside of the same class, like class klass @@var1 end we found out we can not use the class variable like this: klass.var1 we have to create a class function like class klass @@var1 def var1 return @@var1 end end If anyone know how to access a class variable dire...

Hi all, I have the data set df with three varaibles, x1 x2 x3 1 2 5 2 4 1 5 6 0 1 1 2 I want to insert more rows ( eg, 3 rows with value filled with zeros) 1 2 5 2 4 1 5 6 6 1 1 2 0 0 0 0 0 0 0 0 0 Can any body help me out? Thanks

...ve_connections" def self.active_connections #:nodoc: if allow_concurrency Thread.current[''active_connections''] ||= {} else @@active_connections ||= {} end end what the line "@@active_connections ||= {}" means exactly? as I undertands is if the class varaible @@active_connections has a value then return the value, otherwise return {}, but what is {}, a bloc of nothing??? or what?

Am i a total idiot to try and parse out a rails object for javascript in this way? <% for i in interface_items[0].attributes %> var <%= i[0] %> = "<%=h( i[1] )%>" <% end %> Am I missing something really obvious?

Hi, I''m using link_to_remote to trigger an ajax zone, but depends on a varaible, the new zone has different features. before I has a button inside a form. so when I click on the button, I get the value of the variable inside "params". but since I use link_to_remote now, I don''t get any value from params anymore.... Is there some way I can get the data insid...

...about 40,000 rows and 40 variables (columns). I only need about 10 variables form the data set for the analysis at hand. Unfortunately, these 10 variables are not contiguous in the file, for example, the first is position 1-8, the next position 25-27, then 40. Is there a way to read the selected varaibles that I need without reading in the entire data set?

Now I have an address that present in a unsigned long address like the following format: Value* addr = CONST(0xc0008000) But I do not know how to read the data from the above addr varaible. I tried the following three kind of code: 1. Code: Value* addr = CONST(0xc0008000); Value* data = new LoadInst(addr, "", false, bb); Error: Segmentation fault 2. Code( use BotVastInst to vern): Value* addr = CONST(0xc0008000); a = new BitCast...

Hello, when i compiled latest linux 2.6.4 kernel source with gcc 3.3.2 on Linux/x86, i got a few warnings about varaibles beeing compared against constants where the range of the variable is so that the expression is always constant. The explicit comparison has to do with the code for high-uid and gid sheme. attached you will find a diff which does eliminate this error message by introducing an inline function that...

I would like to replace a few varaibles within a data frame. For example, in the dataframe below (contrived) I would like to replace the current housesize value only if the Location is HSV. However, I would like to leave the other values intact. I tried "ifelse", but I don't really need the else condition. test_...

And I validate that the path and options are set. However the route does not work. Is there anything special I need to do to "activate" the route?

...t; foo$coefficients (Intercept) V1 V3 29.47368421 -2.15789474 0.02631579 Why do the foo coefficients not include V3:V3 ? I thought that the variable "V3:V3" has the values of squares of V3 elements, that is, V3:V3 140*140 120*120 .... Am I wrong? If I specify a fouth varaible "V4" with square values of V3, and the formula is y ~ 1 + V1 + V3 + V4, it seems that the foo will give me different in and out-sample predictions. -Luke [[alternative HTML version deleted]]

Hi All, I have 500 variables time series data for 10 years data. I have sorted 10 out of them according to them. Now my group is giving character string. But i want to fetch those varaible data from theoriginal data. How can i do this? Suppose, total is the data of 500*1500 data. Now i sort 10 variables. >grp >"A41" "A48","A489" Now how can i fetch only these three variable data from original data? Thanks, Sumanta. ---------------------...

Hi, when I assign a one row matrix to another variable, then somehow R automatically convert that varaible into a list. For example: > a = matrix (12, 3, 4) > b = a[1,] > b [1] 12 12 12 12 Is there a way to enable R automatically make b as a one row matrix , rather than explicitly assign like matrix (b, ncol=1). I have come across a couple of time, that when I try to check how many rows...

Hello, I want to start testing using the MNP probit function in stead of the lrm function in my current experiment. I have one dependant label and two independent varaibles. The lrm is simple model <- lrm(label ~ val1 + val2) I tried the same thing with the mnp function and got an error that I don't understand model <- mnp(label ~ val1 + val2) I get back an immediate error that tells me, "The number of alternatives should be at least 3" S...
