Figure 2From: Permutation-validated principal components analysis of microarray dataPCA of the cell-cycle data. Plot of the first two components' loadings against each other. Crosses or gene names represent the variable (hybridization) loadings. Colors indicate the cycle phase to which the hybridizations were classified by Spellman et al. [23]. M/G1, yellow; G1, green; S, blue; G2, red; M, brown. The labeled arrays are misclassified CDC hybridizations assigned to new cell-cycle phases by PCA.Back to article page
