Minor typos and other in Lesson 5

[khangquangtran]

Typo 1, near the beginning of Lesson 5:

Note that that row would also be cnsidered a vector. The third column as a whole would be the vector of all ages in our dataset.

"cnsidered" should be replaced by "considered".

Typo 2, before the first Your Turn:

The element in row 3, column 1 in the data frame tg is element 3 in the vector tg$letn. This duality between data frames and vectors is often exploited in R.

Shouldn't it be "the vector tg$len"?

Other: The formatting of the following is a bit strange:

> ?ToothGrowth ``` (The data turn out to be on guinea pigs, with orange juice or Vitamin C as growth supplements.) Let's take a quick look from the command line.

``` r > head(ToothGrowth) len supp dose 1 4.2 VC 0.5 2 11.5 VC 0.5 3 7.3 VC 0.5 4 5.8 VC 0.5 5 6.4 VC 0.5 6 10.0 VC 0.5

Thanks VERY much for all your help.

The formatting seems fine when viewed with the Chrome and Firefox browsers.
