-==Operations with data modes and object types in '''R'''==
-Consulting and changing data modes is very easy. Below some examples for
-checking the data mode of the object ''a'' and change it to as a factor.
-is.numeric(a)
-## [1] TRUE
-is.factor(a)
-## [1] FALSE
-f <- as.factor(a)
-mode(f)
-## [1] "numeric"
-mode(e)
-## [1] "logical"
-An example of transformation from matrix to dataframe was already shown
-in Types of Objects in R. Another option to do the same is shown below. The type
-and the structure (of the ''d'' object) is also shown below.
-d.1 <- as.data.frame(m)
-class(d.1)
-## [1] "data.frame"
-str(d)
-## 'data.frame': 3 obs. of 4 variables:
-##  $ A: num  1 2 3
-##  $ B: num  4 5 6
-##  $ C: chr  "low" "medium" "high"
-##  $ E: num  7 8 9
