R制作具有不同分類級別的因子表對數線性模型

Question

這是我嘗試制作表格的代碼：

table <- data.frame(expand.grid(
    health = factor(c("support", "oppose"), levels = c("support", "oppose")), + 
    information = factor(c("support", "oppose"), levels = c("support", "oppose")), + 
    gender = factor(c("male", "female"), levels = c("support", "oppose")), 
                    count = c(76, 160, 6, 25, 114, 181,  11, 48)))

R unexpected '=' after info說unexpected '=' after info 。 我的教授在課堂上做了一個這樣的例子，他的代碼有效。 我正在嘗試對數據進行對數線性模型

Answer 1

刪除+ s：

table<- data.frame(expand.grid(health=factor(c("support", "oppose"), 
 levels=c("support", "oppose")), information = factor(c("support", 
"oppose"), levels=c("support", "oppose")), gender = factor(c("male", 
"female"), levels=c("support", "oppose")), count=c(76, 160, 6, 25, 114,
 181,  11, 48)))

它們可能來自在 R 控制台中復制/粘貼代碼的回顯，但會給您帶來語法錯誤。
