Hi Group,
I've a vector of 1000 numeric values for which I want to draw a histogram. I've read this vector into R with no variable name.I mean only the 1000 values, which makes V1 the name of the variable by default?? Then I tried

> hist(V1, breaks = "Sturges",
+      freq = NULL, probability = !freq,
+      include.lowest = TRUE, right = TRUE,
+      density = NULL, angle = 45, col = NULL, border = NULL,
+ main = paste("Histogram of" , V1name),
+ V1lim = range(breaks), ylim = NULL,
+ V1lab = V1name, ylab,
+ axes = TRUE, plot = TRUE, labels = FALSE,
+      nclass = NULL)

It gave me this error:
Error in hist(V1, breaks = "Sturges", freq = NULL, probability = !freq,  : 
  object "V1" not found

I don't get what's wrong,( An R beginner)??
