R Time Series plot.ts() -
i trying read in time series , plot.ts(), getting weird results. perhaps did wrong. tried including start , end dates output still wrong. appreciated. thank you.
this code , output:
sales1 <- read.csv("times.csv",header=true) sales1 salest <- ts(sales1) salest plot.ts(salest) output: > sales1 <- read.csv("times.csv",header=true) > sales1 year q1 q2 q3 q4 1 1991 4.8 4.1 6.0 6.5 2 1992 5.8 5.2 6.8 7.4 3 1993 6.0 5.6 7.5 7.8 4 1994 6.3 5.9 8.0 8.4 > salest <- ts(sales1) > salest time series: start = 1 end = 4 frequency = 1 year q1 q2 q3 q4 1 1991 4.8 4.1 6.0 6.5 2 1992 5.8 5.2 6.8 7.4 3 1993 6.0 5.6 7.5 7.8 4 1994 6.3 5.9 8.0 8.4 > plot.ts(salest) looks can't paste plot. instead of 1 graph has 5 separate plots stacked onto each other.
the format of original data difficult use directly time series. try instead:
sales1 <- t(sales1[,-1]) sales1 <- as.vector(sales1) my_ts <- ts(sales1, frequency = 4, start=c(1991,1)) plot.ts(my_ts)
