我試圖在R語言中繪製圖形中的「系統」變量。這是語言變量系統。我得到錯誤消息:「在plot.new()中出現錯誤:圖邊距過大」如何繪製「系統」?plot.new()中的錯誤:圖邊距太大?
這裏是我的代碼:
## Setup the universe, the range of values that we will process.
sets_options("universe", seq(from = 0, to = 40, by = 0.1))
## Setup the Linguistic Variables for BMI, A1C blood pressure & underwriter rating.
variables <-
set(
bmi =
fuzzy_partition(varnames =
c(under = 9.25,
fit = 21.75,
over = 27.5,
obese = 35),
sd = 3.0),
a1c =
fuzzy_partition(varnames =
c(l = 4, n = 5.25, h = 7),
FUN = fuzzy_cone, radius = 5),
rating =
fuzzy_partition(varnames =
c(DC = 10, ST = 5, PF = 1),
FUN = fuzzy_cone, radius = 5),
bp =
fuzzy_partition(varnames =
c(norm = 0,
pre = 10,
hyp = 20,
shyp = 30),
sd = 2.5)
)
## set up rules
rules <-
set(
fuzzy_rule(bmi %is% under || bmi %is% obese || a1c %is% l,
rating %is% DC),
fuzzy_rule(bmi %is% over || a1c %is% n || bp %is% pre,
rating %is% ST),
fuzzy_rule(bmi %is% fit && a1c %is% n && bp %is% norm,
rating %is% PF)
)
## combine to a system
system <- fuzzy_system(variables, rules)
print(system)
plot(system) ## plots variables
函數'sets_options()','fuzzy_system()'等)從哪裏來? – Stibu
當我嘗試繪製某些內容並且繪圖象限太小時,我在RStudio中得到相同的錯誤 - 如果我增加了繪圖象限的尺寸,則錯誤消失。 –
一個選擇是使用'pdf()','png()'或類似的函數來創建一個更大的劇情畫布並直接繪製到一個文件中。 – Mikko
