# HISTORY:
|
| b5de40e6 |
# 2012-05-18
# o Now using stop() instead of throw().
|
| b3f97f6d |
# 2011-11-01
# o CLEANUP: Changed signed=FALSE to signed=TRUE for readBin() calls
# reading 4-byte integers in internal .readCcgDataGroupHeader() and
# .readCcgDataSet().
|
| 6f7db567 |
# 2009-02-10
# o Added internal rawToString() replacing rawToChar() to avoid warnings
# on "truncating string with embedded nul".
|
| 3f8dfde2 |
# 2008-08-23
# o SPEED UP: Removed all gc() calls.
|
| a3b26d44 |
# 2008-01-13
# o Removed dependency on intToChar() in R.utils.
# o BUG FIX/UPDATE: The file format was updated between April 2006 and
# November 2007. More specifically, the so called "Value Types" were
# changed/corrected. Before values 7:9 were 'DOUBLE', 'STRING', and
# 'WSTRING'. Now 7:8 are 'STRING' and 'WSTRING' and there is no longer
# a 'DOUBLE'.
# This was detected while trying to read a CNCHP file outputted by the
# new Affymetrix Genotyping Console 2.0. We can now read these files.
|
| ede2c2f5 |
# 2007-08-16
# o Now it is only readCcg() and readCcgHeader() that are public. The
# other readCcgNnn() functions are renamed to .readCcgNnn().
# o Now the read data is converted according to the mime type. See internal
# readWVT() function. The code is still ad hoc, so it is not generic.
# For instance, it basically assumes that Unicode strings only contain
# ASCII/ASCII-8 characters.
# 2006-11-06
# o Tested on Test3-1-121502.calvin.CEL and Test3-1-121502.calvin.CDF.
|
| 95092fca |
# o Created.
