Hello everyone, I have two problems which I am unable to solve : 1.I am trying to add the  row labels (g1-g2000) to the very left of a data table. The data table is 2000 rows  by 62 columns.I have used the following code. read.table(file="C:\\Documents and Settings\\Owner\\My Documents\\colon cancer1.txt",header=T,row.names=1) rowname(dat) <- paste("g", c(1:nrow(dat)),

Hello everyone, I have a data frame in which I am wanting to eliminate the row labels and then relabel the rows with g1-g2000.I have used the following code: dat<-read.table(file="C:\\Documents and Settings\\Owner\\My Documents\\colon cancer1.txt",header=T,row.names=1) file.show(file="C:\\Documents and Settings\\Owner\\My Documents\\colon cancer1.txt") I thought that this

Hello everyone, I have a question as to what code should be used if one wanted to subset from a dataframe of 7000rows by 38 columns.For example if you wanted to generate a array of 100 by 38 would you not use the following: Z<-(dat,dim=c(100,38)) where dat is the dataframe of 7000by 38 Whenever I do this and type show(Z) I get a output of 100 by 38 they all say "integer,7000" as

Dear R-expert, For histogram function, can we get the table of bin and frequency like in excel, together with the histogram? Therefore, we can check the number of data included. Thank you so much for your attention and help. ____________________________________________________________________________________ [[elided Yahoo spam]]

Hi again all, Several replied ASAP that I also needed reshape loaded and not just reshape2. Hmmm tried that and I had some output but not the correct format. What I need is to run simulations of time overlap between species as per the simulation program data input constraints: The basis for the simulations is a species by _time-use matrix in which species are arranged in rows, and time

Hello, I need to convert dataframe from: ID T0 T1 T2 A 1 2 3 B 4 5 6 C 7 8 9 to: ID Variable Value A T0 1 A T1 2 A T2 3 B T0 4 B T1 5 B T2 6 C T0 7 C T1 8 C T2 9 i tried to use melt cast but it gives me all the time not exactly what I need. Thank

Hello everyone, I have a plot and I am wanting to label points as 1 through 20 I have the following code for the plot: dat<-read.table(file="C:\\Documents and Settings\\Owner\\My Documents\\colon cancer1.txt",header=T,row.names=1) file.show(file="C:\\Documents and Settings\\Owner\\My Documents\\colon cancer1.txt")

Greetings, I need to compare the ratios of vector sizes like this: length(object1) / length(object2) I have many vector objects to compare, so I would like to do it in a loop. I created a loop like this: mat1 <- matrix() for (i in 1:6) { for (j in 1:6) { mat1[i,j] <- length( paste("object",i,sep="")) /

I am trying to cast a Value* irrespective of its underlying subclass to uint64 and pass it on to a method as an argument. if (StoreInst *store_inst = dyn_cast<StoreInst>(&I)) { Value* vo = store_inst->getValueOperand(); uint64 value = /* cast vo to unsigned int 64 bit */ func(value); } How can I force

Is this a recommended approach/good style/good idea to use dyn_cast_or_null<X>(I) instead of dyn_cast_or_null<X>(*I)? (And other is and cast functions).

Hi all, at the moment I am trying to fix an unnecessary iterator dereferencing in Casting.h and am uncovering several ugly things. For example, look at this code: > // dyn_cast_or_null<X> - Functionally identical to dyn_cast, except that a null > // value is accepted. > // > template <class X, class Y> > inline typename cast_retty<X, Y>::ret_type
