Hi, is there a way to take a data frame with 100+ columns and large data set to do efficient exploratory analysis in R with pairs? I find using pairs on the whole matrix is slow and the resulting matrix is tiny. Also the variable of interest for me is a binary var Y or N . Is there an efficient way to graphically view many variable relationships that does not look teeny ? I could do

Hi, is there a way to take a dataset and extract numeric columns and create interaction columns from it automatically? For e.g. there are 5 columns of data: A,B,C,D,E. CDE are numeric. Can someone provide code to automatically create more columns such as: 1) C*D, C*E, C*D*E, (C+E)/(D+.01 (to avoid divide by zero), (D+E)/(C+.01 (to avoid divide by zero), (C+D)/(E+.01 (to avoid

Hi, is there an easy way to get the calculated weights in a regression equation? for e.g. if my model has 2 variables 1 and 2 with coefficient .05 and .6 how can I get the computed values for a test dataset for each coefficient? data var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients

Hi, To pretty print aggregates by various dimensions I needed to add a empty row in output of aggregate. For example. d<-(aggregate(data[,cbind("x")], by=list(data$group1,data$group2), sum)) Group.1 Group.2 x 1 A N 3 2 A Y 2 3 B N 420164905 Is there a way to add an empty

Dear R-people! I??m trying to write a C program that write to the standard input of R and read the standard output. I can perfectly read the R output, but I??m not able of writing anything to R. This program really works with the 'cat?? UNIX command, but it does not work with R. What I??m doing wrong??? It is possible to do it??? I want to start R once and use it thousands of times...

Dear all, I just created this revision <https://reviews.llvm.org/D34937> but I did not receive any email for it even though it says 'Automatically Subscribed' on the right. Also, even my profile shows no trace of the aforementioned revision. It shows that my last activity was on 24th May. Additionally, just to verify that I am not receiving any emails from Phabricator, I logged

Hi, In a binary classification dataset is there a way to tune rpart to now allow any false positives. I.e. is there some setting that will enforce no false positives (prior etc)? (and yet Without making the tree pick all 0 or 1 outcome) Dhruv [[alternative HTML version deleted]]

Hi, Is there a way to get/extract a matrix of regression variable name, coefficient, and p values? (for lm and glm; which can be sort by p value?) thanks Dhruv [[alternative HTML version deleted]]

Device passthrough technology allows a guest to bypass the hypervisor and drive the underlying physical device. VMware has been exploring various ways to deliver this technology to users in a manner which is easy to adopt. In this process we have prepared an architecture along with Intel - NPA (Network Plugin Architecture). NPA allows the guest to use the virtualized NIC vmxnet3 to passthrough to

I am using getSymbols function from quantmod package to get price data from internet. Currently I have: my.ticker <- "IBM" getSymbols(my.ticker,src="google") This creates an xts object named my.ticker which contains historical price data for IBM. How can I call and manipulating this xts object using my original string my.ticker? I want to do: colnames(my.ticker) <-

Hi, Is there a way to save R models (glm, lm , rpart etc) in a file that be read in later? I noticed models take up space. by space them off and removing them from memory it seems that would be useful. Also why do the models keep a copy of all columns in the original data set even those columns are not in the model. E.g. if I build a model on columns A, B even thought column C

I have existing systems with un-encrypted disks. I have tried unsuccessfully to encrypt them using LUKS. Has anyone out there been able to encrypt an existing system (after the fact, so to speak)?

Hi, 1) I have noticed that when I use the aggregate function it outputs numbers in the results. for example: aggregate by product group.1 Aggregate 1 ProductA 1000400.00 2 ProductB 23232323.00 3 Missing 232323.00 is there a way to suppress the numbers infront of aggregate outputs. I checked and they don't look like columns when I do a summary so I can't -1

I have two vectors: both have possible values of 1,-1, or 0 trend1 <- c(1,1,1,1,1,1,-1,-1,-1,-1,-1,-1) trend2 <- c(1,1,1,1,1,1,1,1,1,1,1,1,1,1,) i want to create a third vector that is conditional upon these two vectors: if (trend2 == 1 && trend1 == 1) {position <- 1} elseif (trend2 == -1 && trend1== -1) {position <- 1} else {position <- 0} based on this two
