Dear All- I am trying to merge two data files - they have different date formats and different times zones. I need to match up the date/time of the datasets and then invoke a conditional statement, such as: if dataC$mph is >= 12 then keep dataM$co23 for the corresponding time/date stamp. snippets of data files: *dataC.txt* LST in mph Deg DegF DegF2 % volts Deg

Either that or providing -enable-unsafe-fp-math to llc yielded FMAs. I didn't expect this since using FMAs here instead of mul/add appears to be safer (the reverse is unsafe). ~ Uday

Hello, I have a couple questions about removing rows from a data frame and creating a new data frame with the removed values. I provided an example data frame (d) below. Questions: 1) How can I search for "-999.000" and remove the entire row from data frame "d"? (all -999 values will be in sd_diff) 2) Can I create a new data frame "d.new" that only contains the

I have 100 data files, which contains very huge data sets of location details ( e.g latitude, longitude, time, temp) Now I would like to save the all data of these 100 files in r object, so I can reload data any time. * Every file has different length of data latitude <- NULL longitude <- NULL time <- NULL temp <- NULL for ( i in 1:100) { data<-

Hi, Recently I have installed R version 2.14.1, after installation I am trying to install some packages and I get error message. even I tried install.packages("Rcmdr") but still I am unable to fix this problem. I would be very grateful if somebody can help me to fix this problem. install.packages("hdf5") Installing package(s) into

I got two .RData file e.g data.2005.RData & data.2006.RData I would like to combine these two different data set and make single RData file. in both file there are some NULL files are also available and I would like to clear this NULL files also. $ : NULL $ : NULL $ : num [1:43285, 1:8] -21.1 -21.1 -24.9 -24.9 -24.9 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : NULL ..

I would like to read data from two different folder and then combine this together the code which I have tried are as follows setwd("/Groups/data_first/") file_was <- list.files(path = ".", pattern = "v2.0.2.was", all.files = FALSE, full.names = FALSE, recursive = FALSE, ignore.case = FALSE) path<-c("/Groups/data_second/") file_wasaux2

Thanks Chris for CCing us. I remember Michael's presentation and suggestion to consider Roslyn's design and experience. I'll be glad to discuss further in April. Michael, we can also talk later this week if you'd like. I'll send you a separate email. Loop transformations in MLIR take many different paths. Polyhedral affine-to-affine, generative/lowering in linalg, and also

I have two different datasets 1) is in monthly format (obs) 2) yearly format (model) in obs I have 84 files ( 2003:2009)for different months & in model I have 4 different files which has yearly data (2005:2008) So for calculating my requirement I need these both data sets.

I am dealing with a huge matrix in R (20 columns, 54000 rows) and have lots of missing values within the dataset which are currently displayed as the value "-999.00" I am trying to create a new matrix (or change the existing one) to display these values as "NA" so that I can then perform the necessary analysis on the columns within the matrix. The matrix name is temp and the

Hi all, As a part of work flow, I do a lot of experiments and save all my results into rData file... i.e. at the end of all my experiments, I do "save.image("experiment_name_with_series_number.rData")"... However, some times even with the rData files, I cannot remember the context where these data files were generated. Of course, I can make the R data file names and the R

Hello, On the appended reasonably simple test case that has an fmul/fadd sequence on <8 x float> vector types, I don't see the x86-64 code generator (with cpu set to haswell or later types) turning it into an AVX2 FMA instructions.
