results |
object of class |
file |
character string giving path name for the output file. |
digits |
integer indicating rounding precision for output values. If |
adjust |
character string specifying multiple-testing adjustment method for the t-statistic P-values, e.g., |
method |
character string, should the P-value adjustment be |
F.adjust |
character string specifying adjustment method for the F-statistic P-values. |
quote |
logical value. If |
sep |
the field separator string. Values in the output file will be separated by this string. |
row.names |
logical value, whether to include row names in the output file. |

This function writes a delimited text file containing for each gene (1) the average log2-intensity (AveExpr
), (2) the coefficients or contrasts (log2-fold-changes, Coef
), (3) moderated t-statistics, (4) t-statistic P-values, (5) F-statistic if available, (6) F-statistic P-values if available, (7) decideTests results if available and (8) gene names and annotation.
The results
argument is optional. If supplied, it should be the output from decideTests
for the same fit object, which indicates whether each contrast for each gene is considered statistically significant or not (coded 1 or -1 for positive or negative significant differences and 0 for non-significant values).
If fit
contains row names and row.names=TRUE
, then the row names will be the first column of the output file with a blank column heading.
This behaviour is analogous to that of write.csv
or to write.table
with col.names=NA
.
No value is produced but a file is written to the current working directory.

write.table
or write.csv
in the base library.
