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 !!
