First see if you can read data from the URL with:

fileURL <- "https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data"
myfile <- readLines(fileURL)
head(myfile)

If you can read data from the URL, then the embedded double quotes in the data may be causing your problem.
Try read.csv with the quote parameter:

iris <- read.csv(fileURL, header = FALSE, sep = ",", quote = "\"'")
names(iris) <- c("sepal_length", "sepal_width", "petal_length", "petal_width", "class")
head(iris)
