[R] Extract data of special character

[roslinazairimah zakaria]

Hi Rui and Ivan,
Yes both works well.

table(dd$ATTRIBUTE, dd$TRAIT) #or
xtabs( ~ ATTRIBUTE + TRAIT, dd)

I have another question,I also want to extract all the PCT_SCORE to draw
box plot. I have tried to draw box of PCT_SCORE for all attribute scores.

boxplot(dd$PCT_SCORE, ylim=c(0,100),
        main="Cohort 2015:Distribution of Score % of all attributes",
        xlab="Score(%) of all attribute",horizontal=TRUE,
cex.axis=0.8,cex.main=0.8, cex.lab=0.8, col="lightblue" )

However, I want to draw boxplot for each individual score of the
attributes. That is to extract data of the sub-attribute eg. COMMUNICATION,
CREATIVITY, ENTREPRENEURIAL SKILLS and etc.

Thank you.
