how to plot correlation data in R

Question

[Bioinfonext]

Hi,

I have got spearman's correlation and P value like below in two separate files. Could anyone please suggest how I can make an input file after filtering strong, and significant correlation from these two files? I just want to take pVal<.01,abs(correlation)>.4. and How I can plot it in R?

Correlation.txt

        SB_2    SB_12   SB_17   SB_18   SB_20   SB_23   SB_26
    DMA -0.42   -0.25   -0.06   -0.32   -0.18   -0.18   -0.28
    Rice_AsV-0.67   -0.53   -0.34   -0.67   -0.36   -0.45   -0.34



 Pvalue.txt                             
        SB_2    SB_12   SB_17   SB_18   SB_20   SB_23   SB_26
    DMA 0.001   0.05    0.65    0.016   0.190   0.182   0.03
    Rice_AsV2.87E   3.60E   0.010   2.53E   0.006   0.00    0.00

Hello,

Please take a look at corrplot in R. There is an extensive vignette: https://cran.r-project.org/web/packages/corrplot/vignettes/corrplot-intro.html

Kind regards,
