I am trying to plot data that I imported with read. table using a Weibull
distribution. Here's the code I used for importing the data:
data <- read.table(file =
"C:/Users/Steven/OneDrive/Unfiled/Temp/phase2.csv", header = FALSE, sep = ",",
dec = ".", col.names = c("cycle_time", "cycle_length", "red_time",
"prot_green", "perm_green", "veh_count", "vc", "max_delay", "prot_occ",
"perm_occ", "red5_occ", "gor", "ror", "arrival_time"), na.strings = "NA")
And here's my code for plotting:
curve(dexp(data(arrival_time), rate=0.06), from = 0, to = 60, main =
"Exponential distribution")
I keep getting this error message:
Error in curve(dexp(data(arrival_time), rate = 0.06), from = 0, to = 60, :
'expr' must be a function, or a call or an expression containing 'x'
How to I begin to troubleshoot this? The only thing I can think of is that my
variable of interest, "arrival_time", does contain a number of rows with
blanks, but would that be the underlying cause? If so, can I get the function
to ignore blank rows?
