| //' If you have a huge data frame that you want to do a line-plot of, this | |
| //' function can help down-sample the data to remove consecutive redundancies | |
| //' that would be undetectable in a plot whose resolution is higher than | |
| //' \code{thresh}. It's similar *in spirit* to something like | |
| //' \code{x <- diff(as.matrix(df)); which(apply(x, 1, function(r) any(r>thresh)))}, |
