R Markdown

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:

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

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.

mean(c(1, 2, 3, 4, 5))

## [1] 3

x<- c(1,2,3,4,5,6,4,7,2,9)
plot(x, main = "Жай plot() графигі")

library(ggplot2)
ggplot(data.frame(x = x), aes(x)) + geom_histogram(binwidth = 0.3) + ggtitle("ggplot2 гистограммасы")

summary(x)

##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
##    1.00    2.25    4.00    4.30    5.75    9.00

par(mfrow = c(1,3))

hist(x, main = "Histogram")
boxplot(x, main = "Boxplot")
plot(density(x), main = "Density Plot")
