Does anyone knows a library/technique in R where you can plot a trajectory using multiple timesteps (points) where each point does have a lat/lon coordinate? I have this data
x <- read.table("https://forms.naturwissenschaften.ch/imilast/_ERAinterim_1.5_1979_MTEX/ERAinterim_1.5_NH_M02_19790101_20121231_MTEX.txt?_ga=2.18919096.1825595846.1546710263-1112023567.1546710263", sep="", fill = T, nrows = 1000, header = F, skip = 2) # download only the first 1000 rows colnames(x) <- c("Code","CycloneNo","StepNo","DateI10","Year","Month","Day","Time","LongE","LatN","Intensity1","Intensity2","Intensity3")
Until now I was using a library called esd (developed by Meteo Norway) - which is very nice (github/metno/esd), where there was a function (read.imilast and plot.trajectory), however, that is not the greatest visualization tool). Also, I tried using openair (trajPlot) but that was quite hard to optimize for my data.
I want to plot each trajectory (column
CycloneNo) under a different color if possible and more important, to have like a start and end point for each trajectory.
