我正在运行以下内容来获得预测/拟合值:
library(RCurl)
data <- getURL("https://gist.githubusercontent.com/aronlindberg/a8a6644a639c35ceb9d9/raw/5b7c13bbcd439dacbca70e07c96b6c33804273d2/data.csv")
object <- read.csv(text = data)
mod <- nls(formula = "solution_complexity ~ problem_complexity", data=object, start = list(problem_complexity=0))
predict(mod)
然而,这只给我一个值。如何获得所有预测值?
答案 0 :(得分:1)
如果我这样做
predict(mod, newdata = object[, "problem_complexity", drop = FALSE])
[1] 2 6 4 3 3 4 8 16 7 5 3 12 4 3 9 2 1 5 1 1 4 6 2 5
它似乎有效。
