I want to create a time-based sequence which will mimic the trading window AND would span multiple days. Something like below: "2011-01-03 09:15:00 IST" "2011-01-03 09:15:01 IST" .... .... ....

Hi, I had a query regarding which object, a list or a dataframe, consumes more R memory. Let me clarify this: For example, I have a df of 6 rows and 12 columns, say 'test'. I do object.size() and find it uses 3.3 KB of memory. I run a loop and make a list, say 'testlist', of 6 elements, each element being the above mentioned df 'test'. The size of this list is 19.9 KB,

Dear All, I need to sum a column from another dataframe based on the row values of one dataframe. I am stuck in a loop trying to accomplish it and at current speed it will take more than 80 hours to complete. Needless to say I am looking for a more elegant/quicker solution. Really need some help here. Here is the issue: I have a dataframe CALL (the dput of head is given below) which has close to

Hi All, I am having trouble executing SQL statements on a few dataframes, but the funny thing is that I am able to execute the statement on some other dataframes. To test, I have 2 very small dataframes (6 rows and some columns). One is 'lessliq', the dput is given below. > dput(head(lessliq)) structure(list(V1 = c(50464677L, 50464846L, 50432581L, 50426614L, 50504329L, 50504735L), V2

Hi, I have a query about sqldf, and dates in general. I couldnt find much on the net or on the forums, hence I am here. Here is the issue: I want to write a function that accepts 3 arguments: date1, date2 and a dataframe, say 'df'. Within the function, I want to populate a temp dataframe which essentially contains the output of the query "select * from df where DATE between date1

Create a new alloca instruction, insert it into the IR right before (or after) the old one, RAUW the value, then delete the old instruction. You should be able to find a variety of examples of this sort of thing in most of the IR level optimization passes. I’d look at InstCombine in particular. -Jim On Dec 4, 2013, at 1:40 PM, Shivam Bhagi <shivam.bhagi at outlook.com> wrote: > Hi,

Dear R-users, -I am new to R, and I am struggling with the following problem. -I am repeating the following operations hundreds of times, within a loop: I want to subset a data frame by columns. I am interested in the columns names that are given by the rows of another data frame that was built in parallel. The solution I have so far works well as long as the elements of the second data frame

Hi, While looking over the IR generated by my source code, I came across the following: %arr = alloca [30 x i8], align 1 In the source code this particular line of code is represented by: int arr[30]; I was wondering how I could change the capacity of arr from 30 to any other integral value via a function-pass. I know that 'alloca' can be used for reserving space on stack; further,

Hi, I'm sure some else has been facing this problem. I want to record all the call coming in my queue. I want this format: YYYYMMDD-HHMMSS-AgentID-CallerId - UniqueID. I'm using the monitor feature inside the queue.conf. I can't use the agents.conf monitor features because I'm using dynamic agent (addqueuemember) The problem I'm facing is that I can

Hi lld developers, As a GSoC student I wrote static ld.lld auto-completion scripts for zsh and bash shell because it doesn't have much options and flags for dynamic completion. Whether I send pr to zsh-completion/bash-completion package or open phabricator review for them? Also gnu ld has already autocompletion for bash shell but l am not merging ld and lld completion scripts to one file

How do I parse a date "yyyymmdd"? I tried asking chron(s, "ymd") but that didn't work. Would the date parsing routines of the Date class of 1.9 grok this? -- Ajay Shah Consultant ajayshah at mayin.org Department of Economic Affairs http://www.mayin.org/ajayshah Ministry of Finance, New Delhi

After v1.0 is released, I can finally get back to sane version numbers. But any comments on which one is better: a) Postfix-style: "1.1.UNSTABLE.YYYYMMDD" -> 1.1.0 (stable) b) Odd-even numbering: 1.1.x (unstable) -> 1.2.0 (stable) With a) style the releases could be done by simply copying a nightly snapshot to releases/ directory and announcing the changes since the last

Hi, I have several files with data in this format: 20070102 20070102 20070106 20070201 ... The data is sorted and each line represents a date (YYYYMMDD). I would like to analyze this data using R. For instance, I would like to have a histogram by year, month or day. I've already made a simple Perl script that aggregates this data but I believe that R can be much more powerful and easy on

Hello, I have a simple question. I am trying to load data into a zoo object. I have the data in CSV format as follows SYMBOL DATE TIME PRICE XX YYYYMMDD HH:MM:SS n.nn and there are multiple symbols in this one data frame. My question is, do I need to merge DATE and TIME before loading them or can I specify multiple index.column or index.name fields?
