Hello! I have a program in Fortran and would like to build a matrix with random numbers, I have a function in C. However, I have problems with the use of function in R. Code to compile: R CMD SHLIB mat.f myrbeta.c -o func.so Code in C. #include <R.h> #include <Rmath.h> void F77_SUB(fseedi)(void){   GetRNGstate(); } void F77_SUB(fseedo)(void){   PutRNGstate(); } void

Hello everyone, I'm having a big trouble with which seems to be a bug in as.POSIXct() date-time conversion. I have massive GPS datasets in which each location has it's own date and time attribute. As I convert them to POSIXct format, 1300 cases (of about half a million locations) simply return NA values. I picked up a small sample of failed cases and normal cases to demonstrate the

Hello Vinicius, I did it and this was the answer: ldapsearch -H "ldaps://devsamba.lucas.ufes.br:636" -w '*********' -D "cn=administrator,cn=users,dc=lucas,dc=ufes,dc=br" -x -b "dc=lucas,dc=ufes,dc=br" -d1 ldap_url_parse_ext(ldaps://devsamba.lucas.ufes.br:636) ldap_create ldap_url_parse_ext(ldaps://devsamba.lucas.ufes.br:636/??base) ldap_sasl_bind

Hello everyone, I'm using Samba4 in my CentOS server, and it was just fine. I could always use ldap commands like 'ldapsearch' and 'ldapadd' and I had no problem. But one day, I don't know why, I couldn't use more ldapsearch or ldapadd. They return this: ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) I'm using the same command as always, like:

Hello all: I'm sure this is quite simple, but I tried several options and I still can't get I right. I've got a data.frame and I want to delete all columns of which the sum is zero. Any ideas? Thanks, Frederico Mestre [[alternative HTML version deleted]]

Hello Rowland, You shouldn't use 'ldaps' and ':636', in fact you shouldn't use ':636' at all. OK, mini-howto coming up ;-) The DC is dc1.samdom.example.com The AD domain DN is dc=samdom,dc=example,dc=com There is this line in the DC smb.conf: tls certfile = tls/cert.pem The reverse dns zone has been created and operational The client is

Hello: While running R doing the analysis of my data I (using packages such as BIOMOD or e1071) get the following error as a result of several of my analysis: Error: cannot allocate vector of size 998.5 Mb In addition: Warning messages: 1: In array(c(rep.int(c(1, numeric(n)), n - 1L), 1), d, dn) : Reached total allocation of 4095Mb: see help(memory.size) 2: In array(c(rep.int(c(1,

Hello Brian, Sorry to my late answer, I did what you suggest previously This error suggests a problem with your certificate. If it used to work previously, then check it hasn't expired. openssl s_client -connect devsamba.lucas.ufes.br:636 copy-paste the certificate into a pem file, including begin/end lines openssl x509 -in mycert.pem -noout -enddate And check your root CA

Hello Marc, Thanks for your documentation. Well I followed what you wrote, perhaps my wbinfo command fails when I try to test the connectivity. # wbinfo --ping-dc checking the NETLOGON dc connection failed failed to call wbcPingDc: WBC_ERR_WINBIND_NOT_AVAILABLE Could not ping our DC My smb.conf is now this: # Global parameters [global] netbios name = DEVLUCAS1 realm =

Rowland, I looked at Samba wiki, but it doesn't helped me as I wanted, maybe I'm doing something wrong. This is what I tried to do: yum install pam* ./configure.developer --with-pam make && make install ln -s /usr/local/samba/lib/libnss_winbind.so.2 /lib64/libnss_winbind.so ln -s /lib64/libnss_winbind.so /lib64/libnss_winbind.so.2 modified my nsswitch.conf passwd:

Hello all, I've got a problem with a function in a R package I've developed (MetaLandSim). One of the outputs of my function is the plotting of four images (combining a graph and a map). This plotting is made in a graphical device, with the graph in one side and the map in the other. My function works perfectly fine until it has to plot the map. Then it stops and I get an error.

Dear R community, I'm starting to learn the MS-VAR methodology and I would like to know what I need to download (e.g. packages) to make MS-VAR estimations using R.

I'm implementing a function to compute the moore-penrose inverse, using a code from the article: Fast Computation of Moore-Penrose Inverse Matrices. Neural Information Processing - Letters and Reviews. Vol.8, No.2, August 2005 However, the R presents an error message when I use the geninv. The odd thing is that the error occurs for some arrays, however they have the same size. And the R

Hello: What I want to do is quite simple, but I can't find a way. I have a data frame with several points (x and y coords). I want to add another column with cluster membership. For example aggregate all the points that stand within a distance of 40 from each other. I've tried using "nncluster" from the package nnclust, but the results are not correct, for some
