search for: subgroup2

...r ordering of this data is confirmed by the color coding (black and red in the example) of the subgroup label. Also the "studlab","event" and "n" are all ordered correctly. The probIem now is that I cannot get the added columns ("rnd.subgroup1" and "rnd.subgroup2") to follow this same proper ordering. library(meta) # dummy data nr.studies <- 20 rnd.subgroup1 <- round(rnorm(nr.studies,1.5,.1),0) # random 1s and 2s rnd.subgroup2 <- c(letters[1:nr.studies]) # ordered unique letters lbls <- c(letters[1:nr.studies]) # letters as surroga...

...plicated ones. I have a number of character vectors that look something like this: "12 78 23 9 76 43 2 15 41 81 92 5(92 12) (81 78 5 76 9 41) (23 2 15 43)" I wish to get it into a list of numerical vectors like this: $Group [1] 12 78 23 9 76 43 2 15 41 81 92 5 $Subgroup1 [1] 92 12 $Subgroup2 [1] 81 78 5 76 9 41 $Subgroup3 [1] 23 2 15 43 I can't rely on the closing parenthesis as the last character in the vector, though the subgroup could be clearly defined without it. Numbers are obvious to the eye, but are not always separated from one another consistently. Part of the reason f...
