Dear R-users, I am trying to make a plot with ggplot-geom_tile(), but cannot remove some unwanted (white) lines through my plot. Below a reproducible example: ##### library(ggplot2) tot=as.data.frame(rep(seq(-50,50,5),each=21)) names(tot)="precip" temp=rep(seq(-5,5,0.5),21) tot$temp=temp disc=array(dim=c(21,21)) for(i in 1:21){ for(y in 1:21){ temp<-

Dear R-helpers, I am trying to download some netcdf4 files from the Climate Explorer Website: http://climexp.knmi.nl/start.cgi?id=someone at somewhere In fact, there are 78 distinct files. I have found a way to download a particular file and open it in R, but I have been informed that there exists some code to automatically download all the files. Do you have any clue regarding how to achieve that? Thank yo...

Dear R-users, I am trying to make a plot in R where x and y are plotted in a regular way, but the x axis corresponds to another set of values. For example I have x,y and T (all 29 values) x<- c( -1.31846232, -1.04744756, -0.87034853, -0.72883370, -0.60618971, -0.49501845, -0.39128988, -0.29250120, -0.19694055, -0.10334039, -0.01069355, 0.08185470, 0.17507665, 0.26971270, 0.36651292,

I might run the following: library(ggplot2) #plot scatter and add some hex binning q<-qplot(carat,price,data=diamonds, geom=c("hex"), main="Variability of Diamond Prices by Carat and Colour") #facet to get one scatter for

Hi Listers, Is it possible to produce an ordination plot in 2d, where bubbles represent the location of sites (this part is easy enough) and the size of the bubbles is proportional to the sites location in 3d space (I am stuck on this option). So sites that are very near the 2d plane of the xy axes would be larger while sites that are actually further away in 3 d space would be proportionally

Hello everyone, I was asked to repost this again, sorry for any inconvenience. I'm looking replacement for ddply function from plyr package. Function allows to apply function by category stored in any column/columns. Regular loops or lapplys slow down greatly because my unique combination count exceeds 9000. Is there any available solution which allow me to apply function by category?

I am trying to convert a matlab code to R. Most of the conversion statements are simple, but problem is with return. Since it's a recursive function it's a bit complicated. Anyway in matlab we can have return statment like [price, notional] = functionname() and also for the same function... notional(1) = functionname() how to do this in R? i have tried using data frame but still
