Hi, I need to get in a list the values of p adj of multiple comparisons from Tukey test. I report the part of the script that gives me problems:

for (i in 1:1293) {

p_adjs = rep(NA, 1293)

p_adjs = matrix(p_adjs, nrow=1293, ncol=6)

if (sum(is.na(matrixDataLog[i,]))<3) {

tukey = TukeyHSD(anova)

p_adjall = tukey$Group[,4]  #p-value is in the 4th column of Tukey output

p_adjs[i,1] = p_adjall[1]

p_adjs[i,2] = p_adjall[2]

p_adjs[i,3] = p_adjall[3]

p_adjs[i,4] = p_adjall[4]

p_adjs[i,5] = p_adjall[5]

p_adjs[i,6] = p_adjall[6]

filename = "C:/tukey.txt"

write.table(p_adjs, file=filename, quote=T, sep=" ", dec=".", na="NA")

}

I have an error in p_adjs[i, 1] <- p_adjall[[1]] : number of items to replace is not a multiple of replacement length

But I want to replace one value to one value, so I don't understand. Can anyone help me to solve my problem? Thanks in advance.
