Hello, I have to write a big sentence with cat() and I would like that R automatically adds a new line when it is needed (when the text arrives at the end of the window), the same as Windows Notepad does (Word Wrap). How could I do? Thank you F.

Hello, I have a csv file with many variables, both characters and integers. I would like to load it on R and do some operations on integer variables, the problem is that R loads the entire dataset considering all variables as characters, instead I would like that R makes the distinction between the two types, because there are too many variables to do: x1<-as.integer(x1)

Hi, How to find in a module, the list of functions whose addresses are ever taken into some variables? - Sanjiv

Each function is a GlobalValue. Find all the uses of them... any uses that are not a "call" with the function as callee goes into your list. Global variables work the same way. Find the uses of them that are not "Load" or "Store" instructions with the global value as the pointer operand. On Tue, Sep 8, 2009 at 12:20 PM, Sanjiv Gupta<sanjiv.gupta at

I would like to simulate a stochastic process by specifying an intensity function, say lambda(t)=0.05 + 3 exp(鈭抰) I have the following code, but it has a number of problems. One issue I have is I do not know where the time variable is. I would appreciate your help with this code. library("survival") n <- 5000 lamc<-0.08 k1<-0.05 k2<-3 ld<-function(t){k1+k2}

Unluckily I dela with miRNA files whose name may contain the character "*". Because of the special meaning of "*" I have to remove it. I found out how to make list.files() extract only those file names which contain a "*" Namely: # list.files(pattern="\\*") Now I have to process all files whose name does NOT contain the character "*". I cannot

GuRus How do I use the write function (or write.table or write.csv) to achieve the following please? age=c(32,37,39) names=c("john","peter","jake") I would like create in a directory 3 files each named as john.csv,peter.csv and jake.csv and each file have data from the age vector. That is jon.csv will contain 32, peter.csv will contain 37 and jake.csv will contain

Hi, Let's say I have a data frame (called "example") with numeric values stored (columns V1 and V2). I also have a string variable storing this name x1<-"example" Is there a way to use the variable x so that R knows that I want the specified action to occur on the data frame? For example, summary (x) would return a summary of the data frame? I am considering this
