R devel - Apr 2007 - source(..., echo=TRUE) broken in R-2.5.0 alpha and in R-2.6.0 devel

Hi,

I get this error with R-2.5.0 alpha and R-2.6.0 devel:

  > source("http://bioconductor.org/biocLite.R", echo=TRUE)
  Error in if (timestamp != srcfile$timestamp) warning("Timestamp of
'",  :
          missing value where TRUE/FALSE needed

Same with 'verbose=TRUE':

  > source("http://bioconductor.org/biocLite.R", verbose=TRUE)
  'envir' chosen:<environment: R_GlobalEnv>
  encoding = "native.enc" chosen
  --> parsed 2 expressions; now eval(.)ing them:

  >>>> eval(expression_nr. 1 )
                   ================  Error in if (timestamp !=
srcfile$timestamp) warning("Timestamp of '",  :
          missing value where TRUE/FALSE needed

The above works fine with R-2.4.1.

Cheers,
H.

Indeed, there's a bug 
 iff both 'echo' is TRUE and the ``file'' that is sourced is not
 a proper file (but e.g. a http:// connection).

It looks like the current code in source() and some of its
helper functions such as getSrcLines()
have not yet been "robustified" to work correctly in such a case.

We (R-core) will look at a patch ASAP.

yes, since that automatically uses  echo = TRUE
