[R-sig-Geo] Reverse color in stplot

Dear all I want to reverse color in my spatio-temporal maps that are created with stplot function. How can i solve this problem? Thanks alot Mahsa Sameti [[alternative HTML version deleted]] ___ R-sig-Geo mailing list R-sig-Geo@r-project.org

[R-sig-Geo] Question about wireframe of spatio-temporal emperical variogram

Dear all I'm working on monthly spatio-temporal data. I have constructed STSDF object and then compute empVgm. When i want to plot it, the scale of time axis is based on year. I tested different methods for creating time series for correcting this problem but it shows the time scale only based on

[R-sig-Geo] assigning lower , upper and control arguments

Dear all I have a question about assigning control, lower and upper bounds arguments in fit.stvariogram function. How we should choose them for different covariance models(like separable, metric,...). Thanks alot. [[alternative HTML version deleted]] ___

[R-sig-Geo] Spatio temporal anisotropy

Dear list I'm working on monthly spatio-temporal data. After running emperical spatiotemporal variogram and fitting purely spatial and temporal variograms, i wanted to compute spatio-temporal anisotropy. When i run the function estiStAni(empVgm,interval=spVgmMod$range), this Error will be appear :

[R-sig-Geo] creating xts object

Dear all I’m working with monthly spatio-temporal data. I have a question about creating spatio-temporal object. When I wanted to create time series, I used as.yearmon function. After that when i create purely spatial variogram from empirical spatio-temporal variogram (spEmpVgm <- empVgm[empVgm$t

[R-sig-Geo] vgmST parameters

Dear all When working with vgmST function, how we choose starting values for space, time anf joint vgm? If we should choose them from sample stvariogram, why are they different in different covariance models? I mean, initial values of space and time vgm in separable model is different from sum-met
