source  target 364 448 364 449 364 371 364 372 534 743 534 371

i need calculate correlation (kind of dependency) each pair. made adjunct matrix mentioned format , try calculate correlation , covariance based on 1. result got not correct.

r or other free tool can used fine.

Why does PHP consider 0 to be equal to a string? -

-
i have following piece of code: $item['price'] = 0; /*code item information goes in here*/ if($item['price'] == 'e') { $item['price'] = -1; } it intended initialize item price 0 , information it. if price informed 'e' means exchange instead of sell, indicated negative value because stored in database requires numeric value. there possibility leave price 0, either because item bonus or because price set in later moment. but, when price not set, leaves initial value of 0, if loop indicated above evaluates true , price set -1. is, considers 0 equal 'e'. how can explained? edit: when price provided 0 (after initialization), behavior erratic: if evaluates true, evaluates false. you doing == sorts out types you. 0 int, in case going cast 'e' int. not parseable one, , become 0 . string '0e' become 0 , , match! use ===

so let's have named vector: sorted = c(1,2,3) names(sorted) = c("a","b","c") and it'll following: > sorted b c 1 2 3 so vector named a,b,c, , has value 1,2,3 respectively. and have sample data: data.ex = as.data.frame(matrix(rep(c(1,2,3,4),3), nrow = 3, ncol = 3)) colnames(data.ex) = c("a","b","c") so data frame has 3 columns named a,b,c well. i want predict c using value in glm(): fit.ex = glm(formula = c ~ names(sorted)[2], data = data.ex, family = binomial(link = "logit")) but then, i'll keep getting following error message: error in model.frame.default(formula = c ~ names(sorted)[2], data = data.ex,: variable lengths differ (found 'names(sorted)[2]') i read article here , found as.name() function, still not working: http://www.ats.ucla.edu/stat/r/pages/looping_strings.htm and cannot find else thats similar problem. please, if the...
