Hi I am trying to calculate the row sums of a matrix i have created The matrix ( FeaturePresenceMatrix) has been created by 1) Read csv 2) Removing unnecesarry data using [-1:4,] command 3) replacing all the NA values with as.numeric(0) and all others with as.numeric (1) When I carry out the command TotalFeature <- rowrowSums(FeaturePresenceMatrix, na.rm = TRUE) I get the following

Hi, and sorry for the noob question! I have an unordered list of 4 links where the links use Ajax.Updater in the onclick: onclick="new Ajax.Updater(''ajaxarea'', ''link1.php'', {asynchronous:true, evalScripts:true }); return false;" How would I go about using addClassName and removeClassName to show the current link? Thanks for any help with this.
