Dear R community, I have been spending hours to solve my problem myself but I'm just unable to do it. So excuse me if I demand your time. My problem is, that inside my function, I want to pass...

Just to clarify some of your language here before some others rip you apart, you mean to say you'd like to take a random sample of size 5 and not 5 random samples. Now, I believe you can control...
Hey Everyone! I wanted to carry out Hierarchical clustering using distance matrices i have calculated ( instead of euclidean distance etc.) I understand as.dist is the function for this, but the distances in the dendrogram i got by using the...
Dear R community. I am using the identify() function to identify outliers in my dataset. This is the code I am using: #################################################################### # Function to allow identifying points in the QQ plot (by mouseclicking) qqInteractive <- function(..., IDENTIFY = TRUE) { qqplot(...) -> X abline...

Could I have some suggestions as to how (various ways) I can display my confidence interval results? rm(list = ls()) set.seed(1) func <- function(d,t,beta,lambda,alpha,p.gamma,delta,B){ d <- c(5,1,5,14...
Thank you for your help, even though there was such an obvious mistake, Im sorry for that I have now tried to incorporate your suggested solution, but just as last time (the other post that you referred to), I get...
Dear R-users I need to calibrate kappa, rho, eta, theta, v0 in the following code, see below. However when I run it, I get: y <- function(kappahat, rhohat, etahat, thetahat, v0hat) {sum(difference(k, t, S0, X, r, implvol...
Thank you for your answer. The p.adj argument in the kruskal()-function doesn't seem to change anything... Not even the "bonferroni"-method although it is described as the most conservative one (multiplying all p-values with the number...
Dear community, I have a little problem filling in a vector with loop output. I think the problem is the following: I am caluclating the index which indicates where the loop output should be placed at by a formula. But...
Dear R-users I am trying to find a value for the risk free rate minimizing the difference between a BS call value with impl. volatilities minus the market price of a call (assuming this is just the average bid...
Dear R-users. I am faced with a problem I dont know how to solve. I need to calibrate the Heston stochastic volatility model, and have (to my own belief) created a code for calculating the prices of options by...
Dear R-users I am trying to "vectorize" a function so that it can handle two vectors of inputs. I want the function to use phi (a function), k[1] and t[1] for the first price, and so on...
Hi there, I am doing multiple comparisons for data that is not normally distributed. For this purpose I tried both functions kruskal{agricolae} and kruskalmc{pgirmess}. It confuses me that these functions do not yield the same results although they...
