NULL is coming during running a code

[sharma.swati001]

Hi, I am running the following code -

outcome <- read.csv("outcome-of-care-measures.csv", colClasses = "character")
str(outcome)
complete.cases(outcome)
x <- outcome[complete.cases(outcome), ]
str(x)
summary(outcome)
head(outcome)
ncol(outcome)
nrow(outcome)
names(outcome)
outcome[, 11]
outcome[, 11] <- as.numeric(outcome[, 11])
hist(outcome[, 11])

source("best.R")
best("SC", "heart attack")

The results are -

best("SC", "heart attack")
NULL

NULL is coming only rather than resulting as best hospital so can anyone help me here?/

Thanks

source("best.R")

We don't know what is in your csv file, nor do we know what the best() function is as we don't have the best.R file.
