Hi, I have a problem with a large data set wrapped in a reference class. I do that to access the data by reference from within various functions in a script. # The class definition: setRefClass("data", fields = list(h5_df = "list", training_data = "array",

Hi, I just had my Dell R610 reboot with a kernel panic when I threw a couple of zfs clone commands in the terminal at it. Now, after the system had rebooted zfs will not import my pool anylonger and instead the kernel will panic again. I have had the same symptom on my other host, for which this one is basically the backup, so this one is my last line if defense. I tried to run zdb -e

We''re starting to grow our ZFS environment and really need to start standardizing our monitoring procedures. OS tools are great for spot troubleshooting and sar can be used for some trending, but we''d really like to tie this into an SNMP based system that can generate graphs for us (via RRD or other). Whether or not we do this via our standard enterprise monitoring tool or

Dear, I have a dataset with 4 subjects (see ID in example), and 4 treatment (see TRT in example) which are tested on 2 locations and in 3 blocs. By using Lattice dotplot, I made a graph that shows the raw data per location and per bloc. In that graph, I would like to have a reference line per bloc that refers to the first treatment (T1). However, I can not find how to do that. I can make

Hello all, I hope some of you can come to my rescue, yet again. I have two genetic datasets, and I want one of the datasets to have only the columns that are in common with the other dataset. Here is a toy example (my real datasets have hundreds of columns): Dataset 1: Individual SNP1 SNP2 SNP3 SNP4 SNP5 1 A G T C A 2 T C A G T 3 A C...

I've used the HDF5 library to bring some data into R. THe verbose output looks like this: > hdf5load("hdfGraphWed_Mar_16_13_33_37_2005.hdf",load=T,verbosity=1,tidy=T) Processing object: cprSeats ...... which is a Group Processing object: Seats 0 ...... its a dataset......Finished dataset Processing object: Seats 1 ...... its a dataset......Finished dataset Processing object:

Hi everyone, Suppose I have a 3D array of datasets, where say dimension 1 corresponds to cases, dimension 2 to datasets, and dimension 3 to observations within a dataset. As an example, suppose I do the following: > x <- sample(1:20, 48, replace=TRUE) > datasets <- array(x, dim=c(4,3,2)) Here, for each j=1,2,3, I'd like to think...

Hi, a simple question.. is add dataset not part of zonecfg ? global# zonecfg -z myzone (OK) zonecfg:myzone> add dataset (fails as there is no dataset option) zonecfg:myzone> add zfs (fails as there is no dataset option) Basically how do I add a dataset to a zone ? Thanks Roshan please cc me pererar at visa.com

I am working on a function that will remove outliers for regression analysis. I am stating that a data point is an outlier if its studentized residual is above or below 3 and -3, respectively. The code below is what i have thus far for the function x = c(1:20) y = c(1,3,4,2,5,6,18,8,10,8,11,13,14,14,15,85,17,19,19,20) data1 = data.frame(x,y) rm.outliers =

Dear R Community, I am new to R, and have a question that I suspect may be quite simple but is proving a formidable roadblock for me. I have a large data set that includes water-quality measurements collected over many 24-hour periods. The date and time of sample collection are in a combined Date/Time field in the format yyyy-mm-dd hh:mm:ss. I need to be able to subset the data for analysis of

Hello, I have a dataset with 40 variables, some of them are always 0 (each row). I would like to make a subset containing only the columns which values are not all 0, but I don't know how to do it. I tried: for(cut_column in 1:40) { if(sum(dataset[,cut_column])!=0) { columns_useful<-c(columns_useful,dataset[cut_column]) } } sorted_dataset<-subset(dataset,

Hi everybody, Actually, we know that If we create a dataset in R ,after closing the session the dataset automatically is closed. I tried for creating dataset permanently in R.I am facing the problem of creating permanent dataset. can we create dataset permanently If possible? Could somebody help me out in this aspect,plz? Any help would be appreciated. Thanks in advance. -- View this message

Dear all, I have a question about loading the data to barchart plot. I know this could be a very easy question, but I just can not get my head around. What I need to do is to create a trellis plots barchart style (horizontal bar), with levels of one variable (ie. variable “colour” in my example) as ylab and frequency as xlab on each trellis plot. The trellis plots is separated based on

Hi, actually while opening R console and R commander we see some packages like car and datasets. in this packages we have default datasets are available. example: women and prestige like that. now i created a sales dataset importing from excel, xml or text file. now i want to store that dataset permanently in any one of the package like i mentioned above (car or datasets). now i closed my R...

Our Query: Actually while opening R console and R commander we see some packages like car and datasets. In these packages we have default datasets. For example: "Women" and "Prestige" so on. Now we created a "Sales" dataset importing either from excel, xml or text file. Now we are trying to store that dataset permanently in any one of the packages mentioned above (car...

I was asked by a coworker about recovering destroyed datasets on ZFS - and whether it is possible at all? As a related question, if a filesystem dataset was recursively destroyed along with all its snapshots, is there some means to at least find some pointers whether it existed at all? I remember "zpool import -D" can be used to import whole des...

Hello, I do some computations on datasets that come from climate models. These data are huge arrays, significantly larger than typically available RAM, so they have to be accessed row-by-row, or rather slice-by slice, depending on the task. I would like to make an R package to easily access such datasets within R. The C++ backend is ready...
