I have been trying to put dates from an single column in an excel sheet on the x-axis of a plot for a rollapply correlation function.
cor.fun = function(x){cor(x)[1,2]}
gdp.g <- cbind(economic_data$Global,economic_data$GDP)
gdp.g.corr <- rollapply(as.zoo(gdp.g), FUN=cor.fun, width=1,
by.column=FALSE, align="right")
I've tried to use the below function to plot it but I receive the error message that follows.
plot(economic_data$Year,gdp.g.corr, main="GDP Global",
ylab="Correlation", lwd=2, col="blue")
Error in cor(x) : supply both 'x' and 'y' or a matrix-like 'x'
I'm not sure how to make it so that the date data is compatible with the correlation output or vice versa. There are no error messages until I use 1 for the width. Any other value still provides an output.
Here is some sample data:
Year GDP Global
1949 -0.726 -0.074
1950 10.038 -0.173
1951 15.705 -0.052
1952 5.888 0.028
1953 5.956 0.097
1954 0.342 -0.129
1955 8.944 -0.190
1956 5.611 -0.267
1957 5.494 -0.007
