[R] how to un-crosstabulate data without changing numeric values to text?

I have a large amount of data read in from over 140 excel files in the format of x. r1 to r5 are repeat measures for a given Wavelength and ANWC_NO. I need to rearrange x into 3 columns, ANWC_NO,Wavelegth, value ie ANWC_NOWavelength r1 ANWC_NOWavelength,r2 ANWC_NO
