Gene expression data of rice under salinity stress
Description
This data has gene expression values of 200 genes over 40 microarray samples/subjects for a salinity vs. control study in rice. These 40 samples belong to either of salinity stress or control condition (two class problem). This gene expression data is balanced type as the first 20 samples are under salinity stress and the later 20 are under control condition. The first row of the data contains the samples/subjects labels with entries are 1 and -1, where the labels '1' and '-1' represent samples generated under salinity stress and control condition respectively.
Usage
data("rice_salt")Format
A data frame with 200 genes over 40 microarray samples/subjects.
Details
The data is created by taking 200 genes from the large number of genes from NCBI GEO database. The rows are the genes and columns are the samples/subjects. The first half of the samples/subjects are generated under salinity stress condition and other half under control condition.The first row of the data contains the samples/subjects labels with entries as 1 and -1, where th label '1' and '-1' represents sample generated under salinity stress and control condition respectively.
