#' This is a special R script which can be used to generate a report. You can #' write normal text in roxygen comments. #' #' First we set up some options (you do not have to do this): #+ setup, include=FALSE knitr::opts_chunk$set(collapse = TRUE) #' The report begins here. #+ test-a, cache=FALSE # boring examples as usual set.seed(123) x = rnorm(5) mean(x) #' You can use the special syntax {{code}} to embed inline expressions, e.g. {{mean(x) + 2}} #' is the mean of x plus 2. #' The code itself may contain braces, but these are not checked. Thus, #' perfectly valid (though very strange) R code such as `{{2 + 3}} - {{4 - 5}}` #' can lead to errors because `2 + 3}} - {{4 - 5` will be treated as inline code. #' #' Now we continue writing the report. We can draw plots as well. #+ test-b, fig.width=5, fig.height=5 par(mar = c(4, 4, .1, .1)); plot(x) #' Actually you do not have to write chunk options, in which case knitr will use #' default options. For example, the code below has no options attached: var(x) quantile(x) #' And you can also write two chunks successively like this: #+ test-chisq5 sum(x^2) # chi-square distribution with df 5 #+ test-chisq4 sum((x - mean(x))^2) # df is 4 now #' Done. Call spin('knitr-spin.R') to make silk from sow's ear now and knit a #' lovely purse. # /* you can write comments between /* and */ like C comments (the preceding # # is optional) Sys.sleep(60) # */ # /* there is no inline comment; you have to write block comments */
