[R-es] Ayuda por favor

Saludos, estoy intentando usar la función reprojectHDF() (
http://r-gis.net/?q=ModisDownload).

####
source('ModisDownload.R')
library(raster)
library(RCurl)
path<-"~/R/MODIS/Data/Test"
input<-list.files(path,"*.hdf",all.files=T,recursive=T,full.names=T)
input
outname<-paste(substr(input[1],40,45),".tif",sep='')
outname
reprojectHDF(hdfName=input,filename=outname,MRTpath="~/MRT/bin",
resample_type="NEAREST_NEIGHBOR",
proj_type="GEO",datum='WGS84')
####
Pero me resulta el siguiente mensaje de error:
####> reprojectHDF(hdfName=input,filename=outname,MRTpath="~/MRT/bin",+ resample_type="NEAREST_NEIGHBOR",
+ proj_type="GEO",datum='WGS84')

Cambie mi sintaxis de entrada a:
input<-list.files(path=".",".hdf",all.files=T,recursive=T)

y ahora mi error es:
