[R] Error when reading a SAS transport file

[Jean-Louis Abitbol]

Dear All,

I get the following error when using either SASxport or Hmisc to read an
.xpt file:

> w <- read.xport("D:/consult/Trophos/dnp/base/TRO_ds_20081006.xpt")
Erreur dans factor(x, f$value, f$label) : 
  invalid labels; length 15 should be 1 or 14
> z<- sasxport.get("D:/consult/Trophos/dnp/base/TRO_ds_20081006.xpt")
Erreur dans factor(x, f$value, f$label) : 
  invalid labels; length 15 should be 1 or 14

I don't understand what is wrong with the labels ! Is there a limit for
their length ?
Could the problem be in the formats label ? 

Just in case this might help this is the  output from 
test <- lookup.xport("D:/consult/Trophos/dnp/base/TRO_ds_20081006.xpt") 
print(test)

for the first SAS dataset:
