r中长数学表达
这是我第一次在这里,我并不是很实用,但是我希望我的问题会很清楚,我会找到正确的答案。 我正在尝试计算R:需要长的数学表达式中的元音空间区域(元音的语音度量)。 这是我写的,是我回到的错误类型:
tvsa< - (0.5 *((f2u_patients + f2i_patients) *(f1u_patients -f1i_patients -f1i_patients) - (f2a_patients + f2u_patients) *(F1A_PATIENT /p>
放入“ TVSA< - (0.5 *(((f2u_patients + f2i_patients
)一对括号已经打开,我也尝试了
。
It's my first time here and I'm not really practical, but I hope my question will be clear and I'll find the right answer.
I'm trying to calculate a vowel space area (a phonetic measure for vowels) in R: that requires a long math expression.
Here's what I wrote and the type of error I had back:
tVSA<-(0.5 * ((F2U_patients + F2I_patients) * (F1U_patients - F1I_patients) – (F2A_patients + F2U_patients) * (F1A_patients - F1U_patients) – F2A_patients + F2I_patients) * (F1A_patients - F1I_patients))
Error: unexpected input in "tVSA<-(0.5 * ((F2U_patients + F2I_patients) * (F1U_patients - F1I_patients) –"
What could it be? Obvoiusly each of those names (F2U_patients etc.) corresponds to objects I already defined in R. To me, it also looks like each pair of brackets has been righly opened and closed. I also tried with [] too. Could someone help me find me problem?
Thank you in advance.
