parseHashString: Process a string seperated by hash symbols or a vector (or...

In MSToolkit: The MSToolkit library for clinical trial design

Description

parseHashString constructs a list of numerical vectors from a single string that stores these vectors as comma separated substrings delimited by a hash symbols. Alternatively if it is passed a list or vector of strings each of which is a comma-separated list of numbers, it will produce a list of numerical vectors by processing these strings with parseCharInput

Usage

  parseHashString(input, ..., missingMsg)

Arguments

input	(Required) A string to process
...	(Optional) Additional arguments to pass to parseCharInput. No additional arguments passed by default
missingMsg	(Optional) Message to display if the input is not provided. A standard message is displayed by default

Details

parseHashString does one of four things depending on the arguments passed to it: (1) If the input is a single string composed of commas, numbers and hash symbols, it will split the string into along the hash symbols and then process the resulting strings with parseCharInput. The result will be a list of numerical vectors. For example, parseHashString("1,2\#3,4") will create a list with elements c(1,2) and c(3,4).

(2) If the input is a vector of strings that don't have any hash symbols, it will it will simply apply parseCharInput to each element of the vector and construct a list from the result. Thus the same list created in the previous example could also be created by calling parseHashString(c("1,2", "3,4").

(3) If the input is a list of character strings, it functions essentially the same as in (2).

(4) If the input is a list of numerical vectors, it returns the input without modification.

Value

A list of numerical vectors.

Examples

parseHashString("1.5, 2, 3.2#5, 4.2#10,11")
parseHashString(c("1.5, 2, 3.2","5, 4.2","10,11"))
parseHashString(list("1.5, 2, 3.2","5, 4.2","10,11"))
