similar to: R: Securities earning covariance

Good morning, I am a new R user and I am trying to learn how to use it. I am trying to solve this problem. I have a dataframe df of daily securities (for a year) earnings as follows: SEC_ID DAY EARNING IT0000001 20070101 5.467 IT0000001 20070102 5.456 IT0000001 20070103 4.954 IT0000001 20070104 3.456 .......................... IT0000002 20070101 1.456 IT0000002 20070102 1.345

Good morning, I am facing a problem very easy to solve with a program, but not too easy (at least IMHO) with a "declarative" approach. I have a dataframe df with some information about bank branches with a validity time associated (start date/end date, format YYYY-MM-DD) to some attributes (for example number of employees assigned). The following example will clarify this

Dear R experts, I am trying to solve this problem, related to the possibility of changing the shape of a data frame using a "pivoting-like" function. I have a dataframe df of observations as follows: ID VALIDITY YEAR PROPERTY PROPERTY VALUE A1 2007 P1 V1 A1 2007 P2 V2 A1 2007 P3 V3 A1 2008 P1 V10 A1 2008 P2 V20 A2 2007 P5 V50 A2 2008 P6 V20 A3 2007

Dear R experts, I am currently facing a tricky problem which I have read a lot about in the various R mailing lists without finding exactly what I need. I have a big data frame DF (about 2,000,000 rows) with 7 columns being variables and 1 being a measure (using reshape package nomeclature). There are no "duplicates" in it. Fot each of the variables I have some "rules" to

Dear R experts, I have a problem in modifying one column of a dataframe with a datatime format using a datetime operator. Here is my dataframe A: DATACONT PROVINCIA VALORE 1 2007-12-31 MI 1 2 2007-12-31 PV 2 3 2007-12-31 NA 3 4 2007-12-31 MI 4 5 2007-12-31 RM 5 6 2007-12-31 RM 6 7 2007-12-31 MI 7 8

The question is: can I

For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

Hi all, I recently switched to R version 2.6.2 (from 2.5.0 I was using) on Windows XP. I have a fair amount of previous data saved in the form of "approxfun" objects created by version 2.5.0, with code basically like this: > x <- rlnorm(100,10,2) > f <- approxfun(1:100,x) > f(5) [1] 313811.3 > save(f, file="mytest_approx.Rdata") Now on 2.6.2, when I try to

Hi Duncan, I am running R in MDI mode (with localisation not installed because I need to use RWinEdt), on an Italian version of Windows 2000 Pro.

Hello all, finally I upgraded to dovecot 2.2.10 (that comes with CentOS 7.4). But the problem is still there! Why sieve can't move a message in a public namespace complaining about "Mailbox does not exists"? None of you ever try? Some of you have a working setup? I attach "dovecot -n" output. The sieve script is: require ["fileinto", "envelope",

I have samba3-3.3.12 + ldap (openldap 2.4.21) as users backend.
