this question has answer here: what apply method in scala, used in type definition 1 answer i skimming scala code, , find apply method used in type . example: type common = { def apply: {val func: {} => {val a: a}; val c: c} => {val b: b} } what above code mean? as understand, means common refers types includes apply method. but, questions kind of apply method mean? should inputs of apply method be? also, type common = { def apply({val func: {} => {val a: a}; val c: c} => {val b: b}) } what difference between 2 common type? this known structural type. means describe type structure instead of (only) name. type foo{val a: string} means "something has type foo has val a: string ". {val a: string} same anyref{val a: string} . {} means anyref{} , means same anyref . of course can use structural types in structural type

i doing this: the first scenario: for(int i=0; i<50; i++){ // execute other code here switch(mycustomint){ case 1: case 2: case 3: // execude method1 break; case 4: // execute method2 break; } } the second scenario: for(int i=0; i<50; i++){ // execute other code here } switch(mycustomint){ case 1: case 2: case 3: for(int i=0; i<50; i++){ // execute method1 } break; case 4: for(int i=0; i<50; i++){ // execute method2 } break; } the question: the first scenario runs loop once, check switch statement 50 times. the second scenario runs loop twice, check switch statement once. which better way execute? know in today's technology, difference negligible

i tried using facet_grid() first time. plotted histograms own data, , distribution seemed inaccurate when counted boxes manually on graph. replicated code using mtcars data, , problem seemed persist. here histogram produced ggplot: dfrm <- mtcars dfrm$am <- factor(dfrm$am, levels = c(0,1), labels = c("automatic", "manual")) dfrm$vs <- factor(dfrm$vs, levels = c(0,1), labels = c("v-engine", "straight-engine")) require(ggplot2) ggplot(dfrm, aes(x=dfrm[,"mpg"], fill=dfrm[,"am"], colour=dfrm[,"am"])) + geom_histogram(colour="transparent", position = "identity", alpha=0.2, bins = 10) + facet_grid(. ~ dfrm[,"vs"]) when count manually on histogram, count: v-engine, automatic: 14 v-engine, manual: 4 straight engine, automatic: 5 straight engine, manual: 9 this code counts how many of exist in actual data: require(pastecs) by(data=dfrm$am, indices = dfrm$vs, tabl
