Including Plots
You can also embed plots, for example:
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
Newly hatched 71 chicks were randomly allocated into six groups, and each group was given a different feed supplement. Their weights in grams after six weeks are recorded along with feed types.
str(chickwts)## 'data.frame': 71 obs. of 2 variables:
## $ weight: num 179 160 136 227 217 168 108 124 143 140 ...
## $ feed : Factor w/ 6 levels "casein","horsebean",..: 2 2 2 2 2 2 2 2 2 2 ...aggregate(weight ~ feed, data = chickwts, mean)## feed weight
## 1 casein 323.5833
## 2 horsebean 160.2000
## 3 linseed 218.7500
## 4 meatmeal 276.9091
## 5 soybean 246.4286
## 6 sunflower 328.9167You can also embed plots, for example:
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
We can compare the effects of diet supplements on chick weights.
