Please provide R-code for the following question:
The second argument to `split` can be a list of factors. The result is that all interactions (possible combinations) are used for the groups. In the `ToothGrowth` data set, growth (`len`) is measured for two types of supplements (`supp`) and three doses (`dose`). Split this `len` value into 6 groups.
Solutions
Expert Solution
Gol:
Total 6 combinations
len is split by supp and dose
Rcode:
ToothGrowth
attach(ToothGrowth)
Groups <- split(ToothGrowth$len,
list(ToothGrowth$supp,ToothGrowth$dose))
Groups

Use R programming to resolve this; can you please provide
details on the code?
A) Create a dataframe – comparativeGenomeSize with the following
vectors:
> organism<-c("Human","Mouse","Fruit Fly",
"Roundworm","Yeast")
>
genomeSizeBP<-c(3000000000,3000000000,135600000,97000000,12100000)
> estGeneCount<-c(30000,30000,13061,19099,6034)
B) Print the organism and estGeneCount for Human and
fruitfly.(1)
C) Add a column to this data frame calculating base pairs per
gene. To do this, write a function “genedensity” that takes as
arguments the genomesizeBP and estimatedGeneCount information, and
calculates from this the estimated bp per gene....

Please provide R code along with explanations for the following
exercise:
Mortality rates per 100,000 from male suicides for a number of
age groups and a number of countries are given in the data
suicides2 (R package “HSAUR2”). Use appropriate graphical methods
to comment on what the graphic tells us about the data.

Please do this question in R and show the code too, please.
The alternating current (AC) breakdown voltage of an insulating
liquid indicates its dielectric strength. The article “Testing
Practices for the AC Breakdown Voltage Testing of Insulation
Liquids” (IEEE Electrical Insulation Magazine, 1995: 21–26) gave
the accompanying sample observations on breakdown voltage (kV) of a
particular circuit under certain conditions.

The following R code sorts each vector in a list (lst) and
stores the new list in lst1. The code uses a for loop.
lst <-
list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE))
lst1 <- list()
for(i in 1:length(lst))
{
lst1[[i]] <- sort(lst[[i]])
}
lst1
Which of the following options does the same thing as the given
R code above ?
lst <-
list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE))
library(purrr)
lst1 <- map(lst,sort)
lst1
lst <-
list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE))

3. A bank wants to get new customers for their credit
card. They try two different approaches in their marketing
campaign. The first promises a "cash back" reward, and the second
promises low interest rates. A sample of 500 people is mailed the
first brochure; of these, 125 get the credit card. A separate
sample of 500 people is mailed the second brochure; 150 get the
credit card. Are the two campaigns...

The Book of R (Question 20.2) Please answer using R code.
Continue using the survey data frame from the package MASS for
the next few exercises.
The survey data set has a variable named Exer , a factor with k
= 3 levels describing the amount of physical exercise time each
student gets: none, some, or frequent. Obtain a count of the number
of students in each category and produce side-by-side boxplots of
student height split by exercise.
