Error with correlation plot using insig argument when all values are significant

[jhernand1512]

Please take a look to this error when you try to plot a correlation matrix with all values lower or equal to significant level.
Thank's in advance
Juan

require(Hmisc, quietly = TRUE)
require(corrplot)
p=rcorr(as.matrix(attitude[,1:3]))$P
cor_=cor(attitude[,1:3])
corrplot.mixed(cor_, upper='number',lower='ellipse', p.mat=p,
insig='blank')

Error in symbols(pos.pNew[, 1][ind.p], pos.pNew[, 2][ind.p], inches = FALSE

ind.p has length zero because there is no value greater than significant level.
