Hello, I am trying to write the default "OrchardSprays" R data frame into HDFS using the "rhdfs" package. I want to write this data frame directly into HDFS without first storing it into any file in local file system. Which rhdfs command i should use? Can some one help me? I am very new to R and rhdfs.

Hi, I have requirement to move the data from Linux local path( ex /home/user/sample.txt) to hadoop HDFS using RODBC in R I knew that we can move the data using rhive comamnds like *rhive.put* and *rhive.get *but looking for similar commands using RODBC as well. I would appreciate for your inputs. Regards, Divakar Phoenix, USA [[alternative HTML version deleted]]

Hi All, I'm trying to draw boxplots. I'm having a hard time to get "ticks labels" on multiple panels using 'alternating' option. # R Code: # May not be the best example, please just look into 'scales' option library(lattice) data(OrchardSprays) dta <- subset(OrchardSprays, OrchardSprays$rowpos %in% c(1,2,3)) # Original # This works fine, as you can see

Hello, I plot box plot, and add a point to the box indicating mean. I also add some range to the box width. I want to add legend for both the range (line) and mean (point). However, I cannot add line legend and point legend together. The code looks like the following. (1) First, I tried the following code, however, it plot a line across the point legend("*"). boxplot(count ~ spray,

Hi All, Can anyone please help me with getting a "single title" and "legend" for both the plots in the following R code. I'll eventually be using .wmf file. # R code: library(lattice) p1 <- xyplot(decrease ~ treatment, OrchardSprays, groups = rowpos, type = "a", main="Same title / legend", auto.key = list(space = "right",

Here is an example: The legends (mainly the factor level names) are cut off on the right. Somehow the internal calculation which computes horizontal space for the legend is not flexible enough. ## Call a new graphics window {with default par()s !}: get(getOption("device"))() par(mfrow = c(2,2)) ## part of example(interaction.plot) _improved_ using with() : data(OrchardSprays)

hello everybody, I want to print two plots in one png file, I tried several options but i didn't succeed the first plot (bwplot) print to the defined position, but the second (ggplot) doesn't Any idea? Thanks a lot Christophe # Example: #------------------------------------- library(ggplot2) library(lattice) library(grid) one <- bwplot(decrease ~ treatment, OrchardSprays, groups

Hello all, I wrote a small function to add labels for outliers in a boxplot. This function will only work on a simple boxplot/formula command (e.g: something like boxplot(y~x)). Code + example follows in this e-mail. I'd be happy for any suggestions on how to improve this code, for example: - Handle boxplot.matrix (which shouldn't be too hard to do) - Handle cases of complex

Hi, I cannot seem to get lme4 to work. I have installed the lme4 and Matrix package with apt-get. and both can be found in /usr/lib/R/site-library. When I tried an example for lmer, R could not find the function lmer(), > library(lme4) Attaching package: 'lme4' The following object(s) are masked from package:nlme : getCovariateFormula getResponseFormula

Hi all, I want to retrieve the stats from a 'bwplot' with one factor. I have read the help for 'panel' function and I'm aware of the option 'stats' which defaults to 'boxplot.stats' but I didn't understand it well and therefore I am unable to get what I need. Thanks in advance. Héctor Villalobos Windows XP, R 2.5.0 > bwplot(decrease ~ colpos |

I?m entirely stumped on this particular issue and really hoping someone has some advice for me. I am running a covariant model in lm I would like to give the standard errors or the confidence intervals for the fitted lines. I?ve been using the dataset OrangeSprays where I want lines for each level of treatment over the covariant ?colpos?. I?ve been able to calculate intercepts and slopes for

Hi all! I read R Extensions manual. But still I am not sure how to call R functions from C. Would any of you give me a sample C code to show how to call R functions - for instance, time series functions - from C in the embedded way of C code? [[alternative HTML version deleted]]
