在R中查找下面行中的值

# 创建一个数据框
data <- data.frame(
  name = c("John", "Jane", "Alice", "Bob"),
  age = c(25, 30, 28, 35),
  city = c("New York", "Los Angeles", "Chicago", "Houston")
)

# 使用subset函数查找满足条件的行
result <- subset(data, city == "New York")

# 创建一个数据框
data <- data.frame(
  name = c("John", "Jane", "Alice", "Bob"),
  age = c(25, 30, 28, 35),
  city = c("New York", "Los Angeles", "Chicago", "Houston")
)

# 使用逻辑向量的索引方式查找满足条件的行
result <- data[data$city == "New York", ]
