Quantlet:		readcsvm
Description:		readcsvm reads mixed data from the csv file

Usage:	`z=readcsvm(filename{,separators})`
Input:
	`filename`	name of file
	`separators`	string that contains the data separator in the file (default=";")
Output:
	`z.type`	(p+q) vector types of columns in file
	`z.double`	n x p matrix numerical vectors
	`z.text`	n x q matrix text vectors

Note:

If you read mixed data from a file the original position of the vector in the file gets lost. Thus you will receive 3 matrices which will contain the vectors of one type. It is ensured that, e.g. z.double[,1] was in the file before z.double[,2]. The last parameter z.type contains the recognized type t of the corresponding vector in the file (0 represents number, 1 text vector). Note that even if there is only one text element in some column (other elements in this column are numbers) this column will be represented as a text column. The signs " " or "." are also represented as text. File "example.csv" contains: "hallo;5,4;john" ";4,6; " "hi;;george"

Example:

library("xplore") readcsvm("example.csv")

Result:


Contents of out.type

[1,]        1

[2,]        0

[3,]        1

Contents of out.double

[1,]      5.4

[2,]      4.6

[3,]     +NAN

Contents of out.text

[1,] "hallo" "john"

[2,] "" " "

[3,] "hi" "george"
