[R] can we visualize water flows with 3d in R?

Hi R Users, Is it possible to visualize river flow in 3D (latitude, longitude with respect to depth)? The example of my data looks like. Any suggestions? > dat1 long lat depth flow 1 1015.9 857 1.00 1.50 2 1015.9 857 1.25 1.23 3 1015.9 857 0.50 2.00 4 1015.9 858 0.10 1.95 5 1015.9 858 0.

Re: [R] can we visualize water flows with 3d in R?

Hi Marna, Isn't the conventional way to visualize depth as shades of blue? library(plotrix) depth.col<-color.scale(dat1$depth,extremes=c("lightblue",blue")) Then color the lon/lat rectangles with depth.col Jim On Wed, Oct 12, 2016 at 7:49 PM, Marna Wagley wrote: > Hi R Users, > Is it possibl

Re: [R] can we visualize water flows with 3d in R?

Hi Marna, It's hard to tell exactly what you're looking for, since making "3D" plots of fluid flow has significant interpretative challenges (e.g. how do you see the flow for points that are "inside" the domain?). It is common in fields like oceanography to plot 2D "sections" of the 3D flow -- e.g

[R] barplot beside=TRUE - values differ on scales

Dear group, I have been struggling to barplot two different measurements from one subject. These two measures differ in range. I want to plot row 1 axis on left side and row 2 values on right side. For a given column I want to plot GN and CN next to each other. my dput code is below : structure

Re: [R] barplot beside=TRUE - values differ on scales

I have suspect that the most common answer to this will be 'don't', for all the reasons statisticians don't like mixing vertical scales on the same plot. See http://www.perceptualedge.com/articles/visual_business_intelligence/dual-scaled_axes.pdf for one article on that topic. But if you must,

Re: [R] barplot beside=TRUE - values differ on scales

Adrian, What story are you trying to tell? Or what question are you trying to answer by visualizing these data? How is a bar plot of these numbers going to help? I'm just wondering if perhaps a different visualization might make more sense, for example, a scatter plot of GN vs. CN. m <- struct

Hi Adams, The story I am trying to show visually relationship between GN and CN for every column. Each column represents a patient. In each patient, a particular chromosome region (CN) is either lost (-2 or -1) or gained (1 or 2). Typically if loss (one copy loss - as humans have pair of chromosome

Thanks Duncan. I am sorry I cannot scale second row (d[2,]). I was looking for a way to plot d[2,] values next to d[1,] with a right side axis=4 on right side. -2,-1,0,1,2 thanks Adrian On Wed, Oct 12, 2016 at 12:42 PM, Duncan Murdoch wrote: > On 12/10/2016 12:20 PM, Adrian Johnson wrote: >> >>
