Hi everybody, Question: why are my dataframe and numeric variables a character? I read an excel file via readxl but my dataframe is a character, and numeric variables, eg "yi", are also a character. My excelfile is in English numeric Sometimes the dataframe was indeed a dataframe, but I do not know why it did sometimes. Thank you in advance, Roberto PS I used "guess". The

class("dat") is different from class(dat), which is what you actually want. On 17-11-17, P.

Say I have a dataset that looks like Location Year GW_Elv MW01 1999 546.63 MW02 1999 474.21 MW03 1999 471.94 MW04 1999 466.80 MW01 2000 545.90 MW02 2000 546.10 The whole dataset is at http://doylesdartden.com/ExampleData.csv and I use the code below to do the graph but I want to do it without MW01. How can I

Hello everybody, Data is myd <- data.frame(id1=rep(c("a","b","c"),each=3),id2=rep(1:3,3),val=rnorm(9)) I want to get a cumulative sum over each of id1. trying aggregate does not work myd$pcum <- aggregate(myd[,c("val")],list(orig=myd$id1),cumsum) Please suggest a solution. In real the dataframe is huge so looping with for and subsetting is not a

Hello List! We're having trouble making call deflection on ISDN PRI. We would like to transfer a call to an external extension but keeping the callerid of the caller so it can be presented to the receiver of the transferred call. At the time we're using Zaptel 1.4.5.1, Asterisk 1.4.11 and Digium hardware TE420B. We've ordered the service (CD) from the phone company. The

Hi Simon, Thanks for reposting the example, and looking at it more carefully, I think it is very similar to my first proposal. This was met with some resistance here because it dumps loop information in the vector preheader. Doing it this early, we want to emit this in the vectoriser, puts a restriction on (future) optimisations that transform vector loops to honour/update/support this intrinsic

Invitation accepted, I am happy to help out with reviews, like I did with the previous VP patches. And of course agreed that things should be well defined, and that we shouldn't paint ourselves in a corner, but I don't think that this is the case. And it's not that I am in a rush, but I don't think this change needs to be predicated on a big change landing first like the LV

Hi everyone, This is a graphics question, concerning presentation rather than actually producing figures. After much fiddling I've managed to create bar plots showing error bars. I've put in an x-axis, which goes along all the bars, but doesn't appear between the y-axis and the first bar. I've searched all the resources I have access to but can't find anything addressing this

Many thanks to Nick Ellis, Vadim Kutsyy, Charles Berry, and Bill Dunlap for providing thoughts and alternative solutions to the problem. I have included Nick and Charles' notes in full below and a summary of the others. Thanks also to Bill for telling me about an inconsistency in how the first argument of sample is interpreted. I had ignored this, resulting in a major bug. Each person

We are running a fileserver (Samba version 3.0.10-1.4E.9) on CentOS 4.4. No AD, clients are Windows XP and OS X. Linux acl's are used for access to directories and files. Each top-level folder belongs to a primary group with mode 2770. The acl's restrict access to lower level directories. We need to pass the acl's down the directory tree or else users may have unexpected access to

Hi, I abandoned that approach and followed Eli's suggestion, see somewhere earlier in this thread, and emit an intrinsic that represents/calculates the active mask. I've just uploaded a new revision for D79100 that implements this. Cheers. ________________________________ From: Simon Moll <Simon.Moll at EMEA.NEC.COM> Sent: 18 May 2020 13:32 To: Sjoerd Meijer <Sjoerd.Meijer at

Hi all! I'm going mad about getting my shares mapped to my win2k and winXP machines from my Samba PDC Version 3.0.2 on Debian. Win-machines doesn't seem to execute logon.bat at all, except when i log on as root. I've set the ownership and chmod 0775 all logon.bat files to eatch user on my network. Am i just blind or are there something obvious/very wrong with my config? my smb.conf

Hello, I was trying to fit a generalized logistic curve and my code for testing if the function "nls" is working is like this ####### #define the generalized logistic curve function glogit=function(a, b, c, m, t, x) { tmp = 1/(1 + t * exp(-b * (x - m)))^(1/t) model.func = a + tmp * c #define the gradient vector Z = cbind(1, c*(x-m)*tmp^(t+1)*exp(-b*(x-m)), tmp, -c*b*exp(-b*(x-m))

Hi Hanna, your function is essentially zero outside a short interval around 9. And the help page states: "If the function is approximately constant (in particular, zero) over nearly all its range it is possible that the result and error estimate may be seriously wrong." You could try to integrate over a finite interval, say (7, 12). G?ran Brostr?m On 2018-02-06 19:40, li li wrote:

For a data frame, we can add an additional row or column easily. For example, we can add an additional row of zero and an additional row of column as follows. Is there an easy and similar way to add zeros in each dimension? For example, for array(1:12, dim=c(2,2,3))? Thanks for your help!!

Hi all, The function h below is a function of c and it should be a monotone increasing function since the integrand is nonnegative and integral is taken from c to infinity. However, as we can see from the plot, it is not shown to be monotone. Something wrong with the usage of integrate function? Thanks so much for your help.
