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:

# Defining patient data
subject_name <- c("John Doe", "Jane Doe", "Steve Graves")

temperature <- c(98.1, 98.6, 101.4)
flu_status <- c(FALSE, FALSE, TRUE)

# Correcting factor assignment
gender <- factor(c("MALE", "FEMALE", "MALE"))

# Ensure levels match the values present
blood <- factor(c("O", "AB", "A"), levels = c("A", "B", "AB", "O"))

# Correcting case in blood sign factor
bloodsign <- factor(c("+", "-"), levels = c("+", "-"))

# Ordered factor with correct level sequence
symptoms <- factor(c("severe", "mild", "moderate"), 
                   levels = c("mild", "moderate", "severe"), 
                   ordered = TRUE)

# Correcting data frame creation
pt_data <- data.frame(subject_name, temperature, flu_status, gender, blood, symptoms, 
                      stringsAsFactors = FALSE)

# Check the data frame
print(pt_data)
##   subject_name temperature flu_status gender blood symptoms
## 1     John Doe        98.1      FALSE   MALE     O   severe
## 2     Jane Doe        98.6      FALSE FEMALE    AB     mild
## 3 Steve Graves       101.4       TRUE   MALE     A moderate
pt_data$temp_c<-(pt_data$temperature-32)*(5/9)
pt_data
##   subject_name temperature flu_status gender blood symptoms   temp_c
## 1     John Doe        98.1      FALSE   MALE     O   severe 36.72222
## 2     Jane Doe        98.6      FALSE FEMALE    AB     mild 37.00000
## 3 Steve Graves       101.4       TRUE   MALE     A moderate 38.55556

Including Plots

You can also embed plots, for example:

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