this question has answer here: how join (merge) data frames (inner, outer, left, right)? 12 answers starting use r in data analysis, still relative newbie. have data frame looks this: locations loc idnum 100000001 1 100000009 7 100000021 3 100000004 2 100000017 3 100000007 7 100000067 5 and matrix list of id numbers (from second column) , corresponding strings (like translation table of sorts). looks similar this: names idnum idnames 1 nnw43 2 n3 3 se21 4 sw54 5 w6 6 w12 7 ne10 ... so matrix shorter because each id number has corresponding string, in original data frame there more 1 loc contain same idnum. i'm sure there easy way match each id number string , create new data frame first column same second containing strings instead of id numbers, i'm not sure is. know i'm told if use loops in r you're doing wrong. result

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))) #
