HI, The code was working perfectly fine yesterday and today, until half an hour ago. Couldn't find any problems in the code. Still, I am getting error message.
myMatrix <- data.matrix(read.table(text=" Name Age ANTONY 27 IMRAN 30 RAJ 22 NAHAS 32 GEO 42 ", header=TRUE)) MinMaxArray <- data.frame(MIN = 25,MAX=35) myMatrix[myMatrix$Age<=MinMaxArray$MAX & myMatrix$Age>=MinMaxArray$MIN,] #Error in myMatrix$Age : $ operator is invalid for atomic vectors #Then, I tried Rui's code; inx <- MinMaxArray[[ "MIN" ]] <= myMatrix[, "Age"] & myMatrix[, "Age"]<= MinMaxArray[[ "MAX" ]] myMatrix[ inx , ] Name Age [1,] 1 27 [2,] 3 30 [3,] 4 32 #Previously, this was also working fine. Not sure what is happening.
