问题 I loaded a table like this: V1 V2 V3 pat1 1 2 pat1 3 1 pat1 4 2 pat2 3 3 pat3 1 4 pat3 2 3 and I need to format it into something like the following, with V1 indicating the row, V2 indicating the column, and the values in V3: 1 2 3 4 pat1 2 0 1 2 pat2 0 0 3 0 pat3 4 3 0 0 Please, note that pat1 vs. pat2 vs. pat3 have different numbers of observations and that missing values must be filled with 0. 回答1: Using dcast from reshape2 : library(reshape2) dcast(dat,V1~V2,fill=0) V1 1 2 3 4 1 pat1 2 0

问题 Heyho, I am a beginner in R and have a problem to which I couldn't find a solution so far. I would like to transform dummy variables back to categorical variables. |dummy1| dummy2|dummy3| |------| ------|------| | 0 | 1 |0 | | 1 | 0 |0 | | 0 | 1 |0 | | 0 | 0 |1 | into: |dummy | |------| |dummy2| |dummy1| |dummy2| |dummy3| Do you have any idea how to do that in R? Thanks in advance. 回答1: You can do this with data.table id_cols = c("x1", "x2") data.table::melt.data.table(data = dt, id.vars = id

问题 Not a dup of In Vim, what is the simplest way to join all lines in a file into a single line?, as I specifically mean to use the gq reformatting functionality. I used to write latex in vim using 80 character textwidth . However, I've now switched to an infinite textwidth , so my lines go on forever. Vim's reformatting (gqap for example), combines a few lines into a paragraph, wrapping them at 80 characters. I'd like it to instead combine them into a single line. ie Without a \clang{goto}

It was moved and renamed to and is now located here: Edit > Format > Beautify
