In the Perl script $R_HOME/bin/check there is a bug under the section "Check R
code for syntax errors" where the 'Rfiles <- c(...)' is build up. If there are
too many files in @Rfiles the source code line generated will be too long and
weird things will happen, e.g. strange bytes/characters will be inserted.
SUGGESTION/SOLUTION:
Add a new line character after each "join";
$Rcmd .= join("\",\n \"", @Rfiles) . "\")\n";
instead of
$Rcmd .= join("\", \"", @Rfiles) . "\")\n";
SUGGESTION II:
I ran into similar problems in other situations where I autogenerated too long
source lines. The errors where hard to reproduce and took time to find. It would
be nice if the [R] parser, or some previous engine that reads the source file,
could given an explicit error saying that the "line was too long".
EXAMPLE:
In my case I got in perl '@Rfiles' was:
"R/LogBook.R R/LogEntry.R R/GenePixData.R R/Layout.R R/ImaGeneData.R
R/MicroarrayData.PLOT.R R/QualityData.R R/MicroarrayData.R R/MAData.R
R/MAData.NORM.R R/zzz.R R/Replicates.R R/SMA.R R/FieldFilter.R R/Filter.R
R/QuantArrayData.R R/RGData.R R/RawData.R R/000.R R/MicroarrayData.IO.R
R/LayoutGroups.R R/BFilter.R R/com.braju.sma.R R/Copy of TFilter.R R/Copy of
SSMatrix.R R/private.utils.R R/WangetalData.R R/KHessFilter.R R/DfFilter.R
R/SpotData.R R/ScanAlyzeData.R R/BMAData.R R/AFilter.R R/MFilter.R
R/Layout.obsolete.R R/AndFilter.R R/OrFilter.R R/SEFilter.R R/TFilter.R
R/AcceptFilter.R R/SpotPosition.R R/SerialFilter.R R/GSRArray.R
R/MultiwayArray.R R/KHessData.R R/GeneAcceptFilter.R R/GeneData.R
R/GeneRejectFilter.R R/TMAData.R R/NotFilter.R R/ParallelFilter.R
R/RejectFilter.R R/ReplicateOutlierFilter.R R/WorkData.R R/Matrix.R
R/MicroarrayData.LOG.R R/MicroarrayData.NORM.R R/SSMatrix.R"
but in [R] 'Rfiles' became:
[1] "R/LogBook.R" "R/LogEntry.R"
[3] "R/GenePixData.R" "R/Layout.R"
[5] "R/ImaGeneData.R" "R/MicroarrayData.PLOT.R"

[9] "R/MAData.R" "R/MAData.NORM.R"
[11] "R/zzz.R" "R/Replicates.R"
[13] "R/SMA.R" "R/FieldFilter.R"
[15] "R/Filter.R" "R/QuantArrayData.R"
[17] "R/RGData.R" "R/RawData.R"
[19] "R/000.R" "R/MicroarrayData.IO.R"
[21] "R/LayoutGroups.R" "R/BFilter.R"
[23] "R/com.braju.sma.R" "R/Copy of TFilter.R"
[25] "R/Copy of SSMatrix.R" "R/private.utils.R"
[27] "R/WangetalData.R" "R/KHessFilter.R"

[31] "R/ScanAlyzeData.R" "R/BMAData.R"
[33] "R/AFilter.R" "R/MFilter.R"
[35] "R/Layout.obsolete.R" "R/AndFilter.R"
[37] "R/OrFilter.R" "R/SEFilter.R"
[39] "R/TFilter.R" "R/AcceptFilter.R"
[41] "R/SpotPosition.R" "R/SerialFilter.R"
[43] "R/GSRArray.R" "R/MultiwayArray.R"
[45] "R/KHessData.R" "R/GeneAcceptFilter.R"
[47] "R/GeneData.R" "R/GeneRejectFilter.R"
[49] "R/TMAData.R" "R/NotFilter.R"
[51] "R/ParallelFilter.R" "R/RejectFilter.R"
[53] "R/ReplicateOutlierFilter.R" "R/WorkData.R"
[55] "R/Matrix.R" "R/Micr\b‘_ÜI oarrayData.LOG.R"
[57] "R/MicroarrayData.NORM.R" "R/SSMatrix.R"
Look at the 56 element. Trying to add or remove files, I found that this was
always happening at the same column in the Rfiles row and inferred that this is
due to the maximum line length in [R] source files. Correct?
