similar to: Retrieve all names of nested list and index list based on these names

Hello, I have a nested named list structure, like the following: x <- list( list( list(df1,df2) list(df3, list(df4,df5)) list(df6,df7))) with df1...d7 as data frames. Every data frame is named. Is there a way to get a specific named element in x? so, for example, x[[c("df5")]] gives me the data frame 5? Thank you in advance! Best, Friedericksen

Hello, I'm trying to create a data frame with three columns, one of which is a variable-length list. I tried: df <- data.frame(name = c("a", "b", "c"), type=c(1, 2, 3), rtn = c(list(1,2,3), list(4, 5,6), list(7,8,9, 10) ) ) This would be useful, for example, if the 'rtn' is a variable number of

Dear users, I would like to process all the lists from all *.rda files that I have in one folder. Up to now, I can load all the *.rda files without any problem. The problem is when I want to access the list saved within each *.rda file (only one list per rda file). Here is my code: fpath <- "D:/R" listnames <- list.files(path=fpath, pattern=glob2rx("*.rda"),

Hello all Is there a way reducing the number of characters in a list so that just the left n numbers of characters is given? For example, If I have a list, listnames, which consists of 4 strings of 6 characters; >listnames [1] "item12" "item34" "item56" "item78" Is there a way to reduce this so only the 5 characters on the lefthand side are

Hi, I want to compute the lower triangle of a square matrix (optionally, sans diagonal). With for() loops I can do something like this: ## 5 by 5 matrix rtn for (j in 1:5) { for (k in 1:j) { if (j != k) { ## optional rtn[j, k] <- my.func(j, k) } } } I'd like to do this with apply(). Is there some way I can do this kind of 'short-circuit'? Thanks, Mark Wilkinson

Hi, I apologize if this has previously been posted. I've just subscribed to the R-help digest. I'm writing a plotting function that uses layout() to plot several different plots on the same device. This function uses plot(), image(), and a custom function that uses text(). Each cell of the layout needs different par() parameters, so what I'd like to do is pass them as lists:

Newbie and trying to learn the right way of doing things in R. in this case, I just have that feeling that my convoluted line of code is way more complicated than it needs to be. Please help me in seeing the easier way. I want to do something pretty simple. I have a dataframe called x that is 6945 elements long. I'd like to create a vector rtn= log(x[2,2]/x[1,3]), then log(x[3,2]/x[2,3]),

I'm using list.files() on my home directory, like this: crnt.files <- list.files(dir.to.check, full.names=TRUE, all.files=TRUE, recursive=TRUE) With dir.to.check set to the full path to my home directory. After a while I get: Error in list.files(dir.to.check, full.names = TRUE, all.files = TRUE, : 'translateCharUTF8' must be called on a CHARSXP This happens on one of my

I am trying to write a loop to forecast realized volatility over successive days for the purpose of VaR prediction using the HAR-RV-CJ model which is as follows: log(RV_t+1) = ?_0 + ?_CD log(CV_t) + ?_CW log(CV_t-5) + ?_CM log(CV_t-22) + ?_JD log(J_t + 1) + ?_JW log(J_t-5 + 1) + ?_JM log(J_t-22 + 1) + e_t where RV is realized volatility, CV is continuous volatility and J is the jump which is

Hi Krzysztof, Sure, please see below. DAG.dump.() before and after, annotated with what I believe the DAG means. I've spent some time debugging the method but it's proving difficult to determine where the logic is misfiring. Disabling the entire combine causes a lot of failing x86-64 tests - I may have to learn an upstream vector ISA to make progress on this. Thank you >From your

Hi , For our production package i need to create a dataframein C . So I wrote the following code SEXP dfm ,head,df , dfint , dfStr,lsnm; *SEXP valueVector[2];* char *ab[3] = {"aa","vv","gy"}; int sn[3] ={99,89,12}; char *listnames[2] = {"int","string"}; int i,j; //============================= PROTECT(df = allocVector(VECSXP,2));

Hi , I am trying to create a dataframe in C and sebd it back to R. Can anyone point me to the part of the source code where it is doing , let me explain the problem I am having . -------------------------------------------------------------------- My simple implementation is like this SEXP formDF() { SEXP dfm ,df , dfint , dfStr,lsnm; char *ab[3] =

Should tablegen detect this as an error, or is it documented as a limitation somewhere that we've missed? In the tablegen-generated file AMDILGenIntrinsics.inc, we have a bunch of if statements comparing strings, many of which are dead, preventing correct recognition of some intrinsics in the their text form. I'm not quite sure what GET_FUNCTION_RECOGNIZER is used for, but if it's

Out of curiosity, what is wrong about that? It looks ok to me. -Chris On Nov 29, 2012, at 6:52 PM, "Relph, Richard" <Richard.Relph at amd.com> wrote: > Should tablegen detect this as an error, or is it documented as a limitation somewhere that we've missed? > > In the tablegen-generated file AMDILGenIntrinsics.inc, we have a bunch of if statements comparing

If the source being scanned has "llvm.AMDIL.barrier.global, it will match the first barrier test and return AMDIL_barrier, not AMDIL_barrier_global.

Dear List I have experienced that objects generated with one of my packages used a lot of space when saved on disc (object.size did not show this!). some debugging revealed that formula and call objects carried the full environment of subroutines along, including even stuff not needed by the formula or call. here is a sketch of the problem ,---- | test <- function(x){ | x <-
