how can dplyr minimum (or mean) value of each row on data.frame? mean same result as apply(mydataframe, 1, mean) apply(mydataframe, 1, min) i've tried mydataframe %>% rowwise() %>% mean or mydataframe %>% rowwise() %>% summarise(mean) or other combinations errors, don't know proper way. i know use rowmeans, there no simple "rowmin" equivalent. there exist matrixstats package functions don't accept data.frames, matrixes. if want calculate min rowwise use do.call(pmin, mydataframe) there simple rowwise mean? do.call(mean, mydataframe) doesn't work, guess need pmean function or more complex. thanks in order compare results work on same example: set.seed(124) df <- data.frame(a=rnorm(10), b=rnorm(10), c=rnorm(10)) i suppose trying accomplish: df <- data.frame(a=rnorm(10), b=rnorm(10), c=rnorm(10)) library(dplyr) df %>% rowwise() %>% mutate(min = min(a, b, c), mean = mean(c(a, b, c))) # ...

i'm (still) working on representation of data using parallel-coordinates library github ( https://github.com/syntagmatic/parallel-coordinates#parallel-coordinates )(based on d3.js). at moment i'm facing problem there shadow wich shouldn't exist, after reorder axes. after upload of data website plot looks that: after reordering (switch first axes) plot looks that: here can see shadow between second , third axis, shouldn't there. other shadows work fine (as can see in following picture). there additional one. i checked api description of library if maybe use .shadows() method in wrong way, didn't find anything. although checked issues, stackoverflow , google didn't find helpful. here code: <link rel="stylesheet" type="text/css" href="imports/d3.parcoords.css"> <link rel="stylesheet" type="text/css" href="imports/style.css"> <script src="imports/lib/d3.min.js"...
