This is a sample command for extracting data from vectors. This is a rudimentary introduction to the topic.
Checked with R version 4.2.2.
Example
See the command and package help for details.
###Creating Data##### TestData <- 1:10 #Check TestData [1] 1 2 3 4 5 6 7 8 9 10 ######## #Extraction of the fifth element TestData[5] [1] 5 #Replace the 5th element with 0 TestData[5] <- 0 #Check TestData [1] 1 2 3 4 0 6 7 8 9 10 #Extract even numbers from data #But, 0 is excluded TestData[TestData %% 2 == 0 & TestData != 0] [1] 2 4 6 8 10 #Assign a name to the data names(TestData) <- letters[1:10] #Check TestData a b c d e f g h i j 1 2 3 4 0 6 7 8 9 10 #Extract data by name TestData["e"] e 0 #Extract by range TestData[4:9] d e f g h i 4 0 6 7 8 9
I hope this makes your analysis a little easier !!
