Exporting a plot as a jpg

Hi everyone!

So I’m working in a lab where we analyze periodic waves of light via waveclock and we had a command script that would analyze each column of data, export the analysis values to a table, and make a jpg of the analysis plot.

#Iterate through a data file
for(i in 1:dim(data)[2]){
whatever = waveclock(ts(data[,i], start=0, freq=6),jpg=paste(“plot_num”,i,sep=””))
if( !is.null( whatever$modes ) )
{
output[i,] = unlist( whatever$modes[1,2:8] )
}
}
write.table(output, “wavelet_output.csv”, sep=”,”)

This code works fine with R 2.7.0, with the older versions of waveclock 1.0.0 and Rwave 1.24-1
But does not work with their newer counterparts, I feel the issue is in my script I just don’t know what.

Any help is much appreciated!
