[R] length of 'dimnames' [2] not equal to array extent- For Correlation Plot

[Shivi Bhatia]

Hi Sarah,
Thank you for your help.

I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1,
method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot
library.

Please find the reproducible example:
dput(head(CR1,10))
structure(c(26L, 46L, 39L, 38L, 47L, 59L, 56L, 61L, 43L, 60L,
78L, 63L, 2L, 58L, 8L, 1L, 1L, 9L, 11L, 2L, 1037500L, 46747L,
346300L, 672000L, 729000L, 470800L, 423000L, 72184L, 368022L,
1037500L), .Dim = c(10L, 3L), .Dimnames = list(NULL, c("AGE",
"OLD_CAR_PURCHASE_YRS", "Total.Spend.With.Maruti")))

Please advice if this would help.

Thank you. Shivi
