comment out mo yung mga [1], yun ata yung mga expected output.

tapos yung '+' bago yung "lightblue"

fruits <- "apples, oranges, pears"
nchar(fruits)

substring(fruits, 1, 6)

fruits<- substring(fruits, c(1, 9, 18), c(6, 15, 22))
fruits

paste(5, "apples")

nfruits <- c(5, 9, 2)

paste(nfruits, fruits)

paste(fruits, nfruits, sep = " = ")

colourStrings <- c("green", "blue", "orange", "red", "yellow", "lightblue", "navyblue", "indianred")
grep("red", colourStrings, value = TRUE)

colourStrings <- c("green", "blue", "orange", "red", "yellow", "lightblue", "navyblue", "indianred")
grep("^red", colourStrings, value = TRUE)

grep("red$", colourStrings, value = TRUE)

grep("r+", colourStrings, value = TRUE)

grep("e[2]", colourStrings, value = TRUE)
character(0)
grep("e{2}", colourStrings, value = TRUE)

gsub("red", "brown", colourStrings)
