dplyr packageOpen relevant packages
library(tidyverse) # To use dplyr package1. Examine the structure of the iris data set.
How many observations and variables are in the data set?
str(iris)## 'data.frame': 150 obs. of 5 variables:
## $ Sepal.Length: num 5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9 ...
## $ Sepal.Width : num 3.5 3 3.2 3.1 3.6 3.9 3.4 3.4 2.9 3.1 ...
## $ Petal.Length: num 1.4 1.4 1.3 1.5 1.4 1.7 1.4 1.5 1.4 1.5 ...
## $ Petal.Width : num 0.2 0.2 0.2 0.2 0.2 0.4 0.3 0.2 0.2 0.1 ...
## $ Species : Factor w/ 3 levels "setosa","versicolor",..: 1 1 1 1 1 1 1 1 1 1 ...There are 150 observations and 5 variables in iris
dataset.
2. Create a new data frame iris1 that contains
only the species virginica and versicolor with sepal lengths longer than
6 cm and sepal widths longer than 2.5 cm. How many observations and
variables are in the data set?
iris1 <- iris %>% filter(Species == "virginica" | Species == "versicolor") %>%
filter(Sepal.Length > 6 & Sepal.Width > 2.5)
str(iris1)## 'data.frame': 56 obs. of 5 variables:
## $ Sepal.Length: num 7 6.4 6.9 6.5 6.3 6.6 6.1 6.7 6.1 6.1 ...
## $ Sepal.Width : num 3.2 3.2 3.1 2.8 3.3 2.9 2.9 3.1 2.8 2.8 ...
## $ Petal.Length: num 4.7 4.5 4.9 4.6 4.7 4.6 4.7 4.4 4 4.7 ...
## $ Petal.Width : num 1.4 1.5 1.5 1.5 1.6 1.3 1.4 1.4 1.3 1.2 ...
## $ Species : Factor w/ 3 levels "setosa","versicolor",..: 2 2 2 2 2 2 2 2 2 2 ...There are 56 observations and 5 variables in iris1
dataset.
3. Now, create a iris2 data frame from
iris1 that contains only the columns for Species,
Sepal.Length, and Sepal.Width. How many observations and variables are
in the data set?
iris2 <- iris1 %>% select(Species, Sepal.Length, Sepal.Width)
str(iris2)## 'data.frame': 56 obs. of 3 variables:
## $ Species : Factor w/ 3 levels "setosa","versicolor",..: 2 2 2 2 2 2 2 2 2 2 ...
## $ Sepal.Length: num 7 6.4 6.9 6.5 6.3 6.6 6.1 6.7 6.1 6.1 ...
## $ Sepal.Width : num 3.2 3.2 3.1 2.8 3.3 2.9 2.9 3.1 2.8 2.8 ...There are 56 observations and 3 variables in iris2 data
set.
4. Create an iris3 data frame from iris2 that
orders the observations from largest to smallest sepal length. Show the
first 6 rows of this data set
iris3 <- iris2 %>% arrange(desc(Sepal.Length))
head(iris3)## Species Sepal.Length Sepal.Width
## 1 virginica 7.9 3.8
## 2 virginica 7.7 3.8
## 3 virginica 7.7 2.6
## 4 virginica 7.7 2.8
## 5 virginica 7.7 3.0
## 6 virginica 7.6 3.05. Create an iris4 data frame from iris3 that
creates a column with a sepal area (length * width) value for each
observation. How many observations and variables are in the data
set?
iris4 <- iris3 %>% mutate(Sepal.Area = Sepal.Length*Sepal.Width)
str(iris4)## 'data.frame': 56 obs. of 4 variables:
## $ Species : Factor w/ 3 levels "setosa","versicolor",..: 3 3 3 3 3 3 3 3 3 3 ...
## $ Sepal.Length: num 7.9 7.7 7.7 7.7 7.7 7.6 7.4 7.3 7.2 7.2 ...
## $ Sepal.Width : num 3.8 3.8 2.6 2.8 3 3 2.8 2.9 3.6 3.2 ...
## $ Sepal.Area : num 30 29.3 20 21.6 23.1 ...There are 56 observations and 4 variables in iris4 data
set.
6. Create iris5 that calculates the average
sepal length, the average sepal width, and the sample size of the entire
iris4 data frame and print iris5.
iris5 <- iris4 %>% summarize(Average_Sepal.Length = mean(Sepal.Length, na.rm = T),
Average_Sepal.Width = mean(Sepal.Width, na.rm = T),
Sample_size = n())
print(iris5)## Average_Sepal.Length Average_Sepal.Width Sample_size
## 1 6.698214 3.041071 567. Finally, create iris6 that calculates the
average sepal length, the average sepal width, and the sample size for
each species of in the iris4 data frame and print
iris6.
iris6 <- iris4 %>% group_by(Species)%>%
summarize(Average_Sepal.Length = mean(Sepal.Length, na.rm = T),
Average_Sepal.Width = mean(Sepal.Width, na.rm = T),
Sample_size = n())
print(iris6)## # A tibble: 2 × 4
## Species Average_Sepal.Length Average_Sepal.Width Sample_size
## <fct> <dbl> <dbl> <int>
## 1 versicolor 6.48 2.99 17
## 2 virginica 6.79 3.06 398. In these exercises, you have successively modified
different versions of the data frame
iris1 iris2 iris3 iris4 iris5 iris6. At each stage, the
output data frame from one operation serves as the input fro the next. A
more efficient way to do this is to use the pipe operator %>% from
the tidyr package. See if you can rework all of your previous statements
(except for iris5) into an extended piping operation that
uses iris as the input and generates irisFinal as the
output.
irisFinal <- iris %>% filter(Species == "virginica" | Species == "versicolor") %>%
filter(Sepal.Length > 6 & Sepal.Width > 2.5) %>%
select(Species, Sepal.Length, Sepal.Width) %>%
arrange(desc(Sepal.Length)) %>%
mutate(Sepal.Area = Sepal.Length*Sepal.Width) %>%
group_by(Species)%>%
summarize(Average_Sepal.Length = mean(Sepal.Length, na.rm = T),
Average_Sepal.Width = mean(Sepal.Width, na.rm = T),
Sample_size = n())
print(irisFinal)## # A tibble: 2 × 4
## Species Average_Sepal.Length Average_Sepal.Width Sample_size
## <fct> <dbl> <dbl> <int>
## 1 versicolor 6.48 2.99 17
## 2 virginica 6.79 3.06 399. Create a ‘longer’ data frame using the original iris data set with three columns named “Species”, “Measure”, “Value”. The column “Species” will retain the species names of the data set. The column “Measure” will include whether the value corresponds to Sepal.Length, Sepal.Width, Petal.Length, or Petal.Width and the column “Value” will include the numerical values of those measurements.
longIris <- iris %>% gather(key = "Measure",
value = "Value",
Sepal.Length, Sepal.Width, Petal.Length,Petal.Width)
print(longIris)## Species Measure Value
