Question about pda.fd( ) function in "fda" package

  • 1.  Question about pda.fd( ) function in "fda" package

    Posted 08-13-2015 09:09

    Hello guys,

    I have one question about the pda.fd() function in "fda" package. When I try to set up and implement that function, R keeps giving the error:

    pdaList = pda.fd(xfdlist, bwtlist)
    Error in barray[[i]][, , j] <- as.matrix(eval.fd(tx, bfdij), returnMatrix = returnMatrix) :
    number of items to replace is not a multiple of replacement length

    Then I find a code example online. Here is the link. http://www.psych.mcgill.ca/misc/fda/downloads/FDAfuns/R/demo/handwrit.pda.R

    You may have to change the first line to  data("handwrit") and include the "fda" library.

    And it still gives me the same error even I copy and paste the sample code to R.

    Could you tell me why it will give such result and how to deal with it??

    Thank you very much in advance.
