arrays - Reading data from excel into a vector

Question

How do i read in data from csv files into a vector of vectors.

In other words each row would be a vector and each column would be an element inside the vector. It would be like a 2D array [row][col]

Answer 1

您应该简单地使用现有的 csv 库，例如clojure-csv或data.csv。

例如 data.csv 就像

(require '[clojure.data.csv :as csv]
         '[clojure.java.io :as io])

(with-open [in-file (io/reader "in-file.csv")]
  (doall
    (csv/read-csv in-file)))

（示例取自这里）

csv/read-csvvec将返回一个惰性向量序列，您可以使用（如果您真的需要）将其转换为字符串向量的向量。
