r - Make a matrix of plots with row and column titles - using par(mfrow = c(m,n)) command can create matrix of plots m rows , n columns. in special cases, there pattern in plots, such plots in each column share of import attribute, , plots in each row share different of import attribute. such info can included in title of each of m*n plots individually, repetitive. is there convenient way append column names (only above top row of plots) , row names (only left of left column of plots) in such grid? best solution far: utilize text() command place text outside of left-and-top plots. pretty unsatisfactory, requires many separate commands, , tweaking arguments such srt = 90 create text vertical on left margin, , using xpd = na within of par() . the lattice , ggplot2 packages have tools creating multiple plots in grid. may speed entire process if apply want do. library(lattice) splom( ~ iris[,1:4], data=iris, groups=species ) xyplot( mpg ~ wt | factor(

How does Swift implement ARC in property attributes? - how swift implement arc in property attributes? example, how create string variable utilize re-create instead of strong in swift? you can utilize @nscopying attribute when want copy behaviour objective-c. from swift book: apply attribute stored variable property of class. attribute causes property’s setter synthesized re-create of property’s value—returned copywithzone method—instead of value of property itself. type of property must conform nscopying protocol. the nscopying attribute behaves in way similar objective-c re-create property attribute. however, in specific case of string properties, it's not necessary so. strings value type in swift. such, when existing string assigned new variable, variable stores re-create of string, rather reference existing one. swift’s string type value type. if create new string value, string value copied when passed function or metho
