i trying create form allows people submit email using @msu.edu email. have alert coming when it's not msu.edu email, when use email test@msu.edu not submitting form. function checkmail() { var email = document.validation.email.value.tolowercase(); var filter = /^([\w-]+(?:\.[\w-]+)*)@msu.edu/i; var result = filter.test(email); alert('valid email found: ' + result); return result; } you need escape . there. correct code: function checkmail() { var email = document.validation.email.value.tolowercase(); var filter = /^([\w-]+(?:\.[\w-]+)*)@msu\.edu/i; // ^-- escape dot var result = filter.test(email); alert('valid email found: ' + result); return result; } demo

how apply fold functions finite number of times, instead of folding entire list? example, incomplete fold sum first 3 numbers, leaving rest untouched: foldln 3 (+) [1..5] -- [6,4,5] it seems simple fold on part of list, cons rest of list: foldln :: int -> (a -> -> a) -> [a] -> [a] foldln n f xs = (foldl1 f $ take n xs) : drop n xs result in repl: *main> foldln 3 (+) [1..5] [6,4,5] if worry taking , dropping same list double job, can rewrite splitat : foldln n f xs = (foldl1 f $ fst t) : snd t t = splitat n xs note type of function, can't base fold on foldl , because can't have list [[1,2,3],4,5,6] in haskell.

i'm pretty new r, hope can me! i'm trying simulation bachelor's thesis, want simulate how stock evolves. i've done simulation in excel, problem can't make large of simulation, program crashes! therefore i'm trying in r. the stock evolves follows (everything except $\epsilon$ consists of constants known): $$w_{t+\delta t} = w_t exp^{r \delta t}(1+\pi(exp((\sigma \lambda -0.5\sigma^2) \delta t+\sigma \epsilon_{t+\delta t} \sqrt{\delta t}-1))$$ the thing here stochastic $\epsilon$, represented brownian motion n(0,1). what i've done in excel: made 100 samples size of 40. these samples standard normal distributed: n(0,1). then these outcomes used calculate how stock affected these (the normal distribution represent shocks economy). my problem in r: i've used sample function: x <- sample(norm(0,1), 1000, t) have 1000 samples, distributed. don't know how put these results formula have evolution of stock. can help? using r (di...
