Touble with relevel variables in ggplot-CodePudding

I have done this:

FSH_date$BATCH <- relevel(FSH_date$BATCH, "0050820", "0060820", "0070820",
                          "0080820", "0090820", "0101120", "0111120", "0121320",
                          "0131320", "0010121", "0020121", "0030121", "0040721",
                          "0050721", "0060921", "0070921", "0081021", "0091021",
                          "0101121", "0010122", "0020122", "0030122")

I hoped to get such strict order of factor's level to scatter points but instead I got this output:

levels(FSH_date$BATCH)
 [1] "0050820" "0010121" "0010122" "0020121" "0020122" "0030121" "0030122" "0040721"
 [9] "0050721" "0060820" "0060921" "0070820" "0070921" "0081021" "0090820" "0091021"
[17] "0101120" "0101121" "0111120" "0121220" "0131220" "0131224" "0131225" "0131231"
[25] "0131234" "0131237" "0131243"

The order is not that I've been expecting and scatter is not correct as result. Could anyone help to solve this problem?

CodePudding user response：

Peter, thanks for answer.

the levels of factor in my output as not follow order that I set with relevel function and it makes problem to sort my date in right way.

CodePudding user response：

relevel() only moves one specified level to the top, and all the others one position down. To change the order of all levels as desired, try this:

factor(FSH_date$BATCH, levels = c("0050820", "0060820", "0070820", "0080820", "0090820", "0101120", "0111120", "0121320", "0131320", "0010121", "0020121", "0030121", "0040721", "0050721", "0060921", "0070921", "0081021", "0091021", "0101121", "0010122", "0020122", "0030122"))
