array(c(fruits, cost), dim = c(3, 2, 1), dimnames = list(shop_name, : 'dimnames' [2] 的长度不等于数组范围

Question

fruits = c('Apple', 'Banana', 'Grapes')

cost = c(20,10,30)
  
shop_name = c("Fruits guy", "Champa seller', "Bad mango"")

price = c("cost of fruits")

market_name = c("Jhoom Market")
  
  
shops_info = array(c(fruits, cost), dim=c(3,2,1), dimnames=list(shop_name, price, market_name)) 
  
print(shops_info)

Answer 1

问题是您的第二维尺寸为二。但是，维度名称 price 只有一个条目。 R 期望它有 2 个条目。这会起作用：

fruits = c('Apple', 'Banana', 'Grapes')
cost = c(20,10,30)

shop_name = c("Fruits guy", "Champa seller", "Bad mango")
price = c("cost of fruits", "Entry needed") #adding fictional name
market_name = c("Jhoom Market")


shops_info = array(c(fruits, cost), dim=c(3,2,1), dimnames=list(shop_name, price, market_name)) 

print(shops_info)
, , Jhoom Market

              cost of fruits Entry needed
Fruits guy    "Apple"        "20"        
Champa seller "Banana"       "10"        
Bad mango     "Grapes"       "30"
