In seizureStudy.csv, several variables from a study on the effectiveness of progabide as a treatment for epilepsy are stored. y1 through y4 each represent the number of seizures the patient experience during a successive 2-week period during treatment, Trt represents whether the patient recieved placebo (0) or progabide (1) treatments, and Base represents the base number of seizures the patients had in an 8-week period before either treatment was begun. Create a new variable in the data frame that is the total number of seizures each patient had during the 8-week treatment period. • What limitation(s) are their for comparing the total 8-week siezure count between the placebo and progabide treatments? ● Construct a plot that compares the distribution of the number of siezures in the progabide group before and after treatment. • Construct a plot to show if a relationship between base seizure number and age exists.

using R studio please code the following
Transcribed Image Text:In seizureStudy.csv, several variables from a study on the effectiveness of progabide as a treatment for
epilepsy are stored. y1 through y4 each represent the number of seizures the patient experience during
a successive 2-week period during treatment, Trt represents whether the patient recieved placebo (0) or
progabide (1) treatments, and Base represents the base number of seizures the patients had in an 8-week
period before either treatment was begun.
Create a new variable in the data frame that is the total number of seizures each patient had during
the 8-week treatment period.
• What limitation(s) are their for comparing the total 8-week siezure count between the placebo and
progabide treatments?
● Construct a plot that compares the distribution of the number of siezures in the progabide group
before and after treatment.
• Construct a plot to show if a relationship between base seizure number and age exists.
