This may not be a bug, but seems not yet documented. Some data.frames created with development version 2.5.0, when read in 2.4.1, show error: Error in dim.data.frame(chip23) : negative length vectors are not allowed A dump of the data.frame shows as last code: , row.names = as.integer(c(NA, -7269)), class = "data.frame") This seems related to the new feature of data.frames without rownames. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
