I have a data frame which has the following data. data<-read.table("table.txt",header=TRUE) data
X14A_U133A_StatPairs X14A_U133A_Detection X14B_U133A_Signal 1 AFFX-BioB-5_at 403.0 409.3 2 AFFX-BioB-M_at 757.3 574.4 3 AFFX-BioB-3_at 284.4 327.3 4 AFFX-BioC-5_at 2314.2 1685.3 5 AFFX-BioC-3_at 1574.5 1273.0 6 AFFX-BioDn-5_at 2333.7 1796.8 7 AFFX-BioDn-3_at 13673.9 11463.9 8 AFFX-CreX-5_at 17778.8 15248.8 9 AFFX-CreX-3_at 31056.6 24869.9 i want to extract the first column of names as a matrix and pass it to a String[] type in java. I am using RServe and was able to pass the other two columns to double[] in java but was not able to do so for data[,1] to a String[]. I have to do this in order to access induvidual string names. I tried using RList, but din't work out. Is there no String array available with REXP similar to int array and double array? How can this be done?
