r - replace asterisks in dataframe with NA's -



r - replace asterisks in dataframe with NA's -

here's dataframe df

i'm trying:

df=data.frame(rbind(c(1,"*","*"),c("*",3,"*")) df2=as.data.frame(sapply(df,sub,pattern="*",replacement="na"))

it doesn't work because of asterisk i'm getting mad trying replace it.

you should set total reproducible example, people more inclined help when create easy em. anywho...

dat <- data.frame(a=c(1,2,'*',3,4), b=c('*',2,3,4,'*')) > dat b 1 1 * 2 2 2 3 * 3 4 3 4 5 4 * > as.data.frame(sapply(dat,sub,pattern='\\*',replacement=na)) b 1 1 <na> 2 2 2 3 <na> 3 4 3 4 5 4 <na>

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
