Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

Hi Martin, It is really a 'PATH' problem. After adding C:\Program Files\Graphviz2.20\bin to the 'PATH' environment variable, the Rgraphviz package can be loaded without any error messages. Sorry that I ONLY set my 'PATH' environment variable correctly for R but not for Graphviz. Thank you and Duncan so much for your great help. Howard On Tue Mar 30 18:12:54

Hi All, I entered a R statement, e.g. 1:20 = x or log("a") on an HTML form and passed it to a R-CGI script. Obviously, neither of both is a correct R statement or expression. However, my R-CGI script could not return and report the error message to the Web site even though it received the statement. I tried to use some R built-in functions of try, tryCatch, eval, expression,

What is bothering

Hi All, When I tried to catch a returned value from a R graphical function or command (e.g., plot, lines, points, abline, title, xyplot, etc.), I always get a NULL value if it is executed correctly. For example: x <- c(1,2,3,4,5,9,13,19,36) plot.Comm <- plot(x) # plot.Comm <- try(eval(plot(x))) then plot.Comm has a NULL value. Obviously, this is not a good way to check if or

hi All, ok fine got it. The design of R is such that it will work only if data fits in the main memory. This issue has been taken up many times but it seems it would be very difficult to change the core code hmmm. ok fine. hence if i want to work then i will have to either partition the data or work with columns. thanks to you all - Sayonara With Smile & With Warm Regards :-) G a u

thank you for your quick answer, I'm far of the digits capacity and my values are not the result of a computation. I'm developping a R package to acces a specific data source. And I need precision a few better. How can I do ? When I try this In R console, this is correct and what I need : > my_value <- 29.958334 > my_value == 29.958334 [1] TRUE But I need to do the first

Does something like this get you close: x <- list() keys <- LETTERS[1:6] # create for (i in keys){ x[[i]] <- data.frame(a=1:5, b=1:5, c=1:5) } # output output <- file('tempxx.txt', 'w') for (i in keys){ write.table(i, row.names=FALSE, col.names=FALSE, file=output, quote=FALSE) write.table(x[[i]], file=output, quote=FALSE) } close(output) On Wed, Jul 2,

Hi, I have recently updated from Dovecot 2.2 to 2.3. Since I have noticed that vacation responses from sieve are not working the same anymore. For example, my sieve script looks like this: vacation :days 1 :addresses ["Kippels at hhu.de","julian.kippels at hhu.de"] it used to be that I got a vacation response if I sent a mail to kippels at hhu.de and Kippels at hhu.de. Now

hi Jim, if i partition the file, then for further operation like merging the partitioned files and after that doing some analysis on whole data set would again require the same amount of memory. If i am not able to do or if i am not having memory then i feel there should be serious thinking over the issue of memory handling. hence i am also copying this to r-devel list and i would also would

Hi everyone - This came up within the last day -- Jim's response to Deepankar is pasted below. There are probably lots of reasons, but what is the advantage to using .temp over, say, temp? I often find myself writing temporary objects -- should I use the . preface? What would be the advantages to doing so? Thanks in advance for what will surely be a collection of illuminating responses.

Good working knowledge of a DBMS is almost invaluable when it comes to working with very large data sets. In addition, learning SQL is piece of cake compared to learning R. On top of that, knowledge of another (SQL)
