change quote to Note in vignettes #7177
Description
There are a few places where > is used in vignettes
grep --color=auto -nH --null -e '^>' *Rmd
datatable-benchmarking.Rmd:112:> I'm very wary of benchmarks measured in anything under 1 second. Much prefer 10 seconds or more for a single run, achieved by increasing data size. A repetition count of 500 is setting off alarm bells. 3-5 runs should be enough to convince on larger data. Call overhead and time to GC affect inferences at this very small scale.
datatable-faq.Rmd:112:> `unique()` and `match()` are now faster on character vectors where all elements are in the global CHARSXP cache and have unmarked encoding (ASCII). Thanks to Matt Dowle for suggesting improvements to the way the hash code is generated in unique.c.
datatable-faq.Rmd:118:> The radix sort algorithm and implementation from data.table (forder) replaces the previous radix (counting) sort and adds a new method for order(). Contributed by Matt Dowle and Arun Srinivasan, the new algorithm supports logical, integer (even with large values), real, and character vectors. It outperforms all other methods, but there are some caveats (see ?sort).
datatable-faq.Rmd:324:> When indexing arrays by `[` a single argument `i` can be a matrix with as many columns as there are dimensions of `x`; the result is then a vector with elements corresponding to the sets of indices in each row of `i`.
datatable-faq.Rmd:466:> When a function calling `UseMethod('fun')` is applied to an object with class attribute `c('first', 'second')`, the system searches for a function called `fun.first` and, if it finds it, applies it to the object. If no such function is found a function called `fun.second` is tried. If no class name produces a suitable function, the function `fun.default` is used, if it exists, or an error results.
datatable-joins.Rmd:121:> Please keep in mind that the standard argument order in `data.table` is `dt[i, j, by]`. For join operations, it is recommended to pass the `on` and `nomatch` arguments by name to avoid using `j` and `by` when they are not needed.
datatable-joins.Rmd:443:> `allow.cartesian` is defaulted to FALSE as this is seldom what the user wants, and such a cross join can lead to a very large number of rows in the result. For example, if Table A has 100 rows and Table B has 50 rows, their Cartesian product would result in 5000 rows (100 * 50). This can quickly become memory-intensive for large datasets.
datatable-programming.Rmd:102:> Sorry but I don't understand why too many people even think a string was something that could be evaluated. You must change your mindset, really. Forget all connections between strings on one side and expressions, calls, evaluation on the other side.
in markdown > is for quoting, https://commonmark.org/help/tutorial/05-blockquotes.html but some of these uses re not quotes. (the last one maybe is, and maybe the ones in faq are?)
the uses which are not quotes should be changed to Note: instead of >, following discussion here #7151 (comment)
