Hi All, I have a microarray dataset as follows: expt1 expt2 expt3 expt4 expt 5 gene1 val val val val val gene2 val val val val val . . .. gene15000 val val val val valThe result is from the same organism in four different experiments. Also, there are 4 replicates of each experiment. My aim was to find genes that are statistically significant across the four experiments. I carried out one-way anova as follows:sTest<-read.table("myData.dat",header = T, row.names = 1) group <- gl(4,4,16, label=c("Glucose","Citrate", "Tide","Dawn")) gm1 <- (x~group, data=sTest)I received error messages that "x" is unknown, and did not know how to go further from here.
This appears to be a college homework assignment and as such is quite possibily inappropriate submission to Rhelp. If not, you should post the results of str(sTest).
You should also read the Posting Guide and learn to post in plain text.
