 Usage:  plotir(ir {, optionname1, optionvalue1} {, optionname2, optionvalue2} { ... })  
 
 Input:

  ir                     (N x K^2) matrix, impulse response functions, 
                         each column represents a specific impulse response function 
                         over time. The first K columns of ir are the responses of the 
                         first variable on an impulse in the first, second,...,K-th 
                         variable, the second K columns are the responses of the second 
                         variable on an impulse in the first, second,...,K-th 
                         variable, and so on. The first row is set with time 
                         zero. 
                         
  optionname1 ... optionname10  String. Following option names are valid: 
                         "variables" - user can specify variable names 
                         "impulse" - which impulse variables are plotted 
                         "response" - which response variables should be displayed 
                         "labels" - specify the names labels 
                         "explain" - should the plot matrix be explained?

                         "cb1" - confidence bound 1 
                         "cb2" - confidence bound 2 
                         "cb3" - confidence bound 3 
                         "cb4" - confidence bound 4 
                         
                         
  optionvalue1 ... optionvalue10  values according to the before specified option name. 
                         The following optionvalues are valid. 
                         optionname optionvalue 
                         "variables" - vector of strings, e.g. "ln GNP"|"ln M1"|"r" 
                         default: "y1"|"y2"|...|"yK" 
                         "impulse" - vector of integers, that specifies the impulse 
                         variables that appear in the plot, e.g. 2|3 
                         default: 1|2|...|K 
                         "response" - vector of integers, that specifies the response 
                         variables that appear in the plot, e.g. 1|3 
                         default: 1|2|...|K 
                         "labels" - vector of strings, e.g. "Estimated i.r."|"CI 1" 
                         default: no labels are plotted 
                         "explain" - integer, 0 (no explanation) or 1 (aditional explanation) 
                         default: 1 
                         "scale" - string: "sep", "row", "col", or "all"
