问题 I would like to generate 500 different combination of a,b,and c meeting the following conditions a+ b+ c = 1 and a < b < c here is a basic sample of generating random numbers, however, I need to generate it based on aforementioned conditions. Coeff = data.frame(a=runif(500, min = 0, max = 1), b=runif(500, min = 0, max = 1), c=runif(500, min = 0, max = 1)) 回答1: myrandom <- function(n) { m <- matrix(runif(3*n), ncol=3) m <- cbind(m, rowSums(m)) # rowSums is efficient t(apply(m, 1, function(a)

问题 I have a Google Fusion table and I am trying to add a formula column with a simple if statement. The column TYPE contains numbers 1-5. I want to update a formula column based on the value in the TYPE column. I tried many variations (single quote, double quote, etc) of the following: IF(TYPE=1,'red','yellow') But, it always says invalid formula.

The data in Sheet ‘All’ will be added on to and the new data needs to be copied without duplicating the ones that are already there. 回答1: It's not a big problem. The best thing is to keep things simple and copy everything

问题 I been trying to compare some values in handlebars if statement {{#if value == 'otherValue'}} , obviously unsuccessfully because handlebars do not like this and expecting a string, boolean, or function name. Well that would be ok, but then I tried to pass parameter in the function like you can do with {{action}} helper, and well that didn't workout either, got this in console Error: assertion failed: You must pass exactly one argument to the if helper So then I decided to do this in a View,

问题 i have been writing code so that im able to search if there is a path in a graph and if there is one i would want to print out the path, if there is one i would like to print out all of them. i have a condition that writes the path if the predicate is true but it never prints, how should i go about this? %graph edge(a,b). edge(a,c). edge(b,c). edge(c,d). edge(c,e). edge(d,e). edge(f,g). edge(g,h). % condition allways(X,Y) :- edge(X,Y). % recursion allways(X,Y) :- edge(X,B), allways(B,Y).

问题 I want to generate two data series of size 100 in R, one of which is going to be remission time, tr , from Exp(mean=1) distribution and the other one is going to be survival time, t , from Exp(mean=2.5) distribution. I want them to be negatively correlated (say, the correlation is -0.5). But at the same time I want that R avoids the values of t[i] that are less than tr[i] for data point i , because survival times should be greater than remission times. I have been able to produce some
