My wave file is very large and therefore I downsampled it. However, after downsampling, the length of the right channel has no elements. Below is the code I used to downsample the audio file
a=resamp(a,f=48000,g=1025,output = "Wave")
str(a)
Formal class 'Wave' [package "tuneR"] with 6 slots
..@ left : int [1:623310] 162 140 -99 77 96 -5 -38 155 -125 89 ...
..@ right : num(0)
..@ stereo : logi FALSE
..@ samp.rate: num 1025
..@ bit : num 16
..@ pcm : logi TRUE
