How to bootstrap a function after taking a randomly drawn sample without replacement
r,sample,replicate,statistics-bootstrap
I believe you can do this by making a small change to your code as so. extractDiff <- function(P){ sampleset = sample(nrow(P), 15, replace=FALSE) #select the first 15 rows, note replace=FALSE subA <- P[sampleset, ] # takes the 15 selected rows subB <- P[-sampleset, ] # takes the remaining rows...
How to duplicate div by checking box?

you can try something like this HTML <div class="input-container"> <input class="question" placeholder="Question" type="text"/> </div> <div class="add-option">+</div> JS //click the '+' sign $(".add-option").click(function(){ //find the first input and clone it then append it to the container $(".input-container input:first").clone().appendTo(".input-container"); //clear any value from the next input had there been any added $(".input-container...
Quick way to space fill column 256 chars SQL-Server 2012
sql,database,sql-server-2012,fill,replicate
In addition to REPLICATE you can also use SELECT SPACE(256); As far as "the column expanding", the column will not appear expanded in SSMS unless you click on 'Results in Text' (instead of grid). If you use the LEN function it will return 0, but DATALENGTH will return either the...
Python 3 Self replicating file into random directory - then running file
python,python-3.x,random,replicate
You can get list of all dirs and subdirs, and shuffle it in random as follows: import os import random all_dirs = [x[0] for x in os.walk('/tmp')] random.shuffle(all_dirs) for a_dir in all_dirs: print(a_dir) # do something witch each directory, e.g. copy some file there. ...
Laravel 4.2 replicate including child items
save() just returns a boolean if saving worked or not. What you should do instead is this: $new = Order::find($idorder)->replicate(); $new->save(); $itemstemp = DB::table('item')->where('order_id', '=' ,$new->id)->get(); // and so on... Also I think your logic is a bit wrong. Something like that would make more sense to me: $new =...
Accuracy of comparison of runtime
If you check the source code of replicate you will see that is this: > replicate function (n, expr, simplify = "array") sapply(integer(n), eval.parent(substitute(function(...) expr)), simplify = simplify) <bytecode: 0x000000000b3b1ee8> <environment: namespace:base> Since it uses sapply in its source code then yes it is sequential as sapply is actually a...
Using function “cat” with “replicate” in R
As an alternative, you could use sapply instead of replicate: Data <- rnorm(20,20,3) N <- 1000 f <- function(i) { Data.boot <- sample(Data, replace=TRUE) cat("\r", i, "of", N) mean(Data.boot) } outcome <- sapply(1:N, f) or alternatively, using plyr, you could use raply with the progress option (if your main purpose...
Easily replicate an element in Prolog :)
list,prolog,duplicates,replicate
A recursive approach would be straight-forward and would work. I recommend figuring that one out. But here's a fun alternative: repl(X, N, L) :- length(L, N), maplist(=(X), L). If N is instantiated, then length(L, N) will generate a list of length N of just "blanks" (don't care terms). Then maplist(=(X),...
