It’s not the most exciting function ever but I find it quite useful when my screen is wide and short. It simply cuts the data set horizontally into equal size pieces and puts them side by side. Lazy I know!

#'boxMe #' #'Turns an overly long data frame into something easier to look at #' #' @param d A dataframe or matrix #' @param nrow The number of rows you would like to see in the new dataframe #' @examples #' test.set<-data.frame(x=rnorm(100), y=rnorm(100)) #' boxMe(test.set, 18) #' #' library(ggplot2) #' boxMe(diamonds, 10) boxMe<-function(d, nrow){ # Number of rows and columns r<-dim(d)[1] c<-dim(d)[2] rem<-r %% nrow # Number of blank rows reps<-floor(r/nrow) # Number of folds s<-seq(1, reps*nrow, by=nrow) # Breaks box<-d[1:nrow,] # First col for (i in s[-1]){ ap<-d[i:(i+nrow-1),] box<-cbind(box, ap) } #Append remainder if (rem>0){ n.null.rows<-nrow-rem rem.rows<-d[(reps*nrow+1):r,] null.block<-as.data.frame(matrix(rep(NA, (n.null.rows*c)), nrow=n.null.rows)) names(null.block)<-names(rem.rows) last.block<-rbind(rem.rows, null.block) box<-cbind(box, last.block) } return(box) }
