how are you doing
if(!file.exists("./midtermdata")){dir.create("./midtermdata")}
and then this command really brings forhte the following outouts:
str(data) function (…, list = character(), package = NULL, lib.loc = NULL, verbose = getOption(“verbose”), envir = .GlobalEnv)

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:
summary(cars)
## speed dist
## Min. : 4.0 Min. : 2.00
## 1st Qu.:12.0 1st Qu.: 26.00
## Median :15.0 Median : 36.00
## Mean :15.4 Mean : 42.98
## 3rd Qu.:19.0 3rd Qu.: 56.00
## Max. :25.0 Max. :120.00
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.
