-Vignettes are long form documentation commonly included in packages. Because they are part of the distribution of the package, they need to be as compact as possible. The `html_vignette` output type provides a custom style sheet (and tweaks some options) to ensure that the resulting html is as small as possible. The `html_vignette` format:
+Essa *vignette* tem como objetivo fazer a análise dos conjuntos de dados

+## Delineamento Inteiramente Casualizado
+
+Considere os dados disponíveis na página 62 referentes à valores
+fictícios de um experimento de alimentação de porcos no qual se usou 4
+níveis do fator ração. O experimento foi instalado em um delineamento
+inteiramente casualizado com 5 animais (unidades experimentais) para
+cada nível de ração. A variável resposta medida foi o ganho de peso dos
+animais (kg).
+
+Esses dados fazem parte do pacote `legTools` e estão no *data frame*
+`wgpigs`. Alternativamente, pode-se fazer o download do mesmo no formato
+texto separado por tabulação.
+
+```{r}
+## url <- "http://blog.leg.ufpr.br/~leg/legTools/dataset/wgpigs.txt"

-Note the various macros within the `vignette` setion of the metadata block above. These are required in order to instruct R how to build the vignette. Note that you should change the `title` field and the `\VignetteIndexEntry` to match the title of your vignette.
