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:

data<-c(1,2,3,4,5,6)
data
## [1] 1 2 3 4 5 6
Vstring<-c('a','b','c')
headings<-list(NULL, c("a", "b", "c"))
headings
## [[1]]
## NULL
## 
## [[2]]
## [1] "a" "b" "c"
m<-matrix(data, nrow=2, ncol=3,byrow=TRUE, dimnames=headings)
m
##      a b c
## [1,] 1 2 3
## [2,] 4 5 6
m2<-matrix(data, nrow=2, ncol=3,byrow=TRUE, dimnames=headings)
m2
##      a b c
## [1,] 1 2 3
## [2,] 4 5 6
m3<-matrix(data, nrow=3, ncol=3,byrow=TRUE, dimnames=headings)
## Warning in matrix(data, nrow = 3, ncol = 3, byrow = TRUE, dimnames = headings):
## data length differs from size of matrix: [6 != 3 x 3]
m3[1]
## [1] 1
m3[3,2]
## b 
## 2
a<-list(aa=1, bb=2, cc=3)
a
## $aa
## [1] 1
## 
## $bb
## [1] 2
## 
## $cc
## [1] 3
a$aa
## [1] 1
years <- c(1980, 1985, 1990)
scores <- c(34, 44, 83)
df <- data.frame(years, scores)
df[,1]
## [1] 1980 1985 1990
df$cores
## NULL
a<-66
if (a>55){print("a is more than 55")}else {print("a is less than or equal to 55")}
## [1] "a is more than 55"
mylist <- c(55, 66, 77, 88, 99)
for (value in mylist) {print(value)}
## [1] 55
## [1] 66
## [1] 77
## [1] 88
## [1] 99
a <- 100
while (a<500){
  a<- a + 100
  print(a)
}
## [1] 200
## [1] 300
## [1] 400
## [1] 500

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
