<p>Find SAGE Tags with evidence of differential expression by choosing libraries (more than one) to compare across. A large R value indicates differential expression.

sage_tag_library_name |
Click the + to select specific experiments or use the tree box to select all for the chosen organism. Provide one or more values. Use comma as a delimter. |
sage_tag_min_r |
Choose a minimum R value to be returned. Stekel et al.???s R-statistic (Stekel, Git, and Falciani 2000) scores SAGE tags on differential expression among libraries (more variable tags have higher R values), with no assignment of significance values. |
o-fields |
Single valued attributes of the feature. Provide one or more values. Use comma as a delimter. |
o-tables |
Multi-valued attributes of the feature. Provide one or more values. Use comma as a delimter. |
.convert |
a logical value or a function that controls how the result of the method is returned. If this is a function, the character string or raw vector is passed to this function and it converts it appropriately. If this is a logical value and |
.url |
the URL for the Web request. This defaults to the correct value, but can be specified by the caller if the method is available at a different URL, e.g. locally or in a mirror server. |
.json |
a logical value controlling whether to use the JSON or the XML version of the method |
