Suppose that I'm working on Hadley's diamond dataset and I want to review the relationship between price, colour and carat. 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

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<-

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

Hi   I have a problem for saving grid file in R. I want to save a grid file as "tif".   I write this: writeGDAL(predict.grid, 'predict.tif')   after running, I don't recieve any error.

Hi When we use the sav_gol command in R , it shows an error which says: " error in as.matrix". We've downloaded the necessary packages. Kindly help us with this issue. If there is any other function to perform Savitzky-Golay smoothing in R, please let me know. With Regards Reynolds

Hi, Sorry for my ignorance, but how can I see if a function is 'compiled code' or plain R? E.g. the daisy function from the cluster package.

Hi everybody, my problem is the following: I have a function which produces for an input number a dataframe with a fixed number of columns and 0 to 10 rows. Now i want to apply this function to a vector with different inputs and merge all these result-dataframes in one data.frame. Can i give a data.frame-reference to the function, so that the result of the function is not returned but appended

Dear Sir, Please help me to open my rda files. It's urgent to see the content and even if I looked for solutions i didn't find one.

Hi there, I have a complex math equation which does not have a closed form solution. It is - y <- (p*exp(-a*d)*(1-exp((d-p)*(a-x[1]))))/((p-d)*(1-exp(-p*(a-x[1])))) For this equation, I have all the values except for x[1]. So I need to solve this problem numerically. Can anyone suggest an optimization package that I can use to estimate the value for x[1]? Thanks in advance, Diviya

Dear R users, Just to clarify. I am not offering to pay someone to do my Dissertation. These 4-5 commands on Kalman Filter would be only a tiny part of my 10,000 words dissertation. A part that even after trying for a few days, I am still stuck on. I am offering ?50, just to say thanks. Regards -- View this message in context:
