latex - create an explanation of a table in R -

-

i have latex table generated inside pdf r data frame after statistical test , want create summary of table explain significant variables inside it. how can done ??

that's table :

  \hline  & & b & c & d & e \\    \hline & 1.00 & 0.00 & 0.00 & 0.00 & 0.02 \\    b & 0.00 & 1.00 & 0.00 & 0.08 & 0.40 \\    c & 0.00 & 0.00 & 1.00 & 0.00 & 0.00 \\    d & 0.00 & 0.08 & 0.00 & 1.00 & 0.99 \\    e & 0.02 & 0.40 & 0.00 & 0.99 & 1.00 \\     \hline

note : significant varaibles variables have value bigger 0.7 , e.g (d , e have value =0.99 ) signifcant. want summary text under table (e.g variables d , e similar | , e "weakly similar" (0.02) t less similar c) , , want put * on significant numbers , , numbers came data frame in r

thanks in advance

see if want. there more efficient ways go doing this, without details structure of data - bit of mind reader's game know need. having said that, seems want assuming data comes data.frame:

require(xtable) #sample data set.seed(1) dat <- data.frame(matrix(abs(rnorm(25)), ncol = 5   , dimnames = list(letters[1:5], letters[1:5])))   xtable(apply(dat, c(1,2), function(x)      ifelse(x > .7, paste(round(x,3), "**", sep = ""),      ifelse(x > .5, paste(round(x,3), "*" , sep = ""),round(x,3))) ))

produces:

% latex table generated in r 2.12.2 xtable 1.5-6 package % tue apr 12 21:23:31 2011 \begin{table}[ht] \begin{center} \begin{tabular}{rlllll}   \hline  & & b & c & d & e \\    \hline & 0.626* & 0.82** & 1.512** & 0.045 & 0.919** \\    b & 0.184 & 0.487 & 0.39 & 0.016 & 0.782** \\    c & 0.836** & 0.738** & 0.621* & 0.944** & 0.075 \\    d & 1.595** & 0.576* & 2.215** & 0.821** & 1.989** \\    e & 0.33 & 0.305 & 1.125** & 0.594* & 0.62* \\     \hline \end{tabular} \end{center} \end{table} >

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
