plot.ts: putting data in right order and adding labels

Question

[image of current time series graph] 1This is my dataframe: structure(list(MY = c("01 13", "01 14", "01 15", "01 16", "01 17", "01 18", "01 19", "01 20", "01 21", "02 12", "02 14", "02 15", "02 16", "02 17", "02 18", "02 19", "02 20", "02 21", "03 11", "03 12", "03 13", "03 14", "03 15", "03 16", "03 17", "03 18", "03 19", "03 20", "03 21", "04 10", "04 13", "04 15", "04 16", "04 17", "04 18", "04 19", "04 20", "04 21", "05 11", "05 13", "05 14", "05 15", "05 16", "05 17", "05 18", "05 19", "05 20", "05 21", "06 13", "06 14", "06 15", "06 16", "06 17", "06 18", "06 19", "06 20", "06 21", "07 13", "07 14", "07 15", "07 16", "07 17", "07 18", "07 19", "07 20", "07 21", "08 12", "08 13", "08 14", "08 15", "08 16", "08 17", "08 18", "08 19", "08 20", "08 21", "09 13", "09 14", "09 15", "09 16", "09 17", "09 18", "09 19", "09 20", "10 14", "10 15", "10 16", "10 17", "10 18", "10 19", "10 20", "11 11", "11 13", "11 14", "11 15", "11 16", "11 17", "11 18", "11 19", "11 20", "12 14", "12 15", "12 16", "12 17", "12 18", "12 19", "12 20"), n = c(1L, 2L, 12L, 100L, 359L, 79L, 69L, 188L, 132L, 1L, 2L, 9L, 97L, 230L, 76L, 78L, 188L, 127L, 1L, 2L, 8L, 4L, 21L, 120L, 156L, 76L, 76L, 159L, 170L, 1L, 120L, 50L, 180L, 109L, 149L, 47L, 49L, 88L, 3L, 19L, 1L, 43L, 212L, 103L, 210L, 67L, 29L, 151L, 7L, 4L, 43L, 142L, 86L, 289L, 41L, 57L, 402L, 1L, 11L, 83L, 113L, 98L, 116L, 96L, 64L, 263L, 1L, 3L, 13L, 68L, 134L, 75L, 94L, 86L, 72L, 156L, 3L, 3L, 88L, 144L, 129L, 113L, 125L, 77L, 9L, 75L, 162L, 124L, 90L, 103L, 99L, 1L, 1L, 3L, 91L, 232L, 102L, 70L, 51L, 118L, 4L, 72L, 208L, 5196L, 50L, 73L, 105L), percent = c(0.0068903741473162, 0.0137807482946324, 0.0826844897677944, 0.68903741473162, 2.47364431888652, 0.54433955763798, 0.475435816164818, 1.29539033969545, 0.909529387445738, 0.0068903741473162, 0.0137807482946324, 0.0620133673258458, 0.668366292289671, 1.58478605388273, 0.523668435196031, 0.537449183490664, 1.29539033969545, 0.875077516709157, 0.0068903741473162, 0.0137807482946324, 0.0551229931785296, 0.0275614965892648, 0.14469785709364, 0.826844897677944, 1.07489836698133, 0.523668435196031, 0.523668435196031, 1.09556948942328, 1.17136360504375, 0.0068903741473162, 0.826844897677944, 0.34451870736581, 1.24026734651692, 0.751050782057466, 1.02666574795011, 0.323847584923861, 0.337628333218494, 0.606352924963826, 0.0206711224419486, 0.130917108799008, 0.0068903741473162, 0.296286088334597, 1.46075931923103, 0.709708537173569, 1.4469785709364, 0.461655067870185, 0.19982085027217, 1.04044649624475, 0.0482326190312134, 0.0275614965892648, 0.296286088334597, 0.9784331289189, 0.592572176669193, 1.99131812857438, 0.282505340039964, 0.392751326397023, 2.76993040722111, 0.0068903741473162, 0.0757941156204782, 0.571901054227245, 0.77861227864673, 0.675256666436987, 0.799283401088679, 0.661475918142355, 0.440983945428237, 1.81216840074416, 0.0068903741473162, 0.0206711224419486, 0.0895748639151106, 0.468545442017502, 0.923310135740371, 0.516778061048715, 0.647695169847723, 0.592572176669193, 0.496106938606766, 1.07489836698133, 0.0206711224419486, 0.0206711224419486, 0.606352924963826, 0.992213877213533, 0.88885826500379, 0.77861227864673, 0.861296768414525, 0.530558809343347, 0.0620133673258458, 0.516778061048715, 1.11624061186522, 0.854406394267209, 0.620133673258458, 0.709708537173569, 0.682147040584304, 0.0068903741473162, 0.0068903741473162, 0.0206711224419486, 0.627024047405774, 1.59856680217736, 0.702818163026252, 0.482326190312134, 0.351409081513126, 0.813064149383312, 0.0275614965892648, 0.496106938606766, 1.43319782264177, 35.802384069455, 0.34451870736581, 0.502997312754083, 0.723489285468201)), class = c("tbl_df", "tbl", "data.frame"), row.names = c(NA, -107L))

I would like to do a timetrend graph of my monthly data.The MY variable represents the month and year of the data e.g. 01 13, is Jan 2013. First of all, I would like the the MY to be in the right order, e.g. I want it to go like: 01 2011, 02 2011,03 2011....etc (I want all the months to be there even if n=0 for that month). Then I want to plot it using plot(as.ts(s)), but I want the labels for each month to be in the x-axis. Right now my plot is not in the right order and there are no labels plot(as.ts(s))
